Biophotonics Success and Future: Where Have We Been and Where Do We Go Next?

Since before the first studies of Endre Mester with the Ruby laser where he showed accelerated wound healing, biophotonics has demonstrated transformational solutions in Medicine. This talk will present a review of several successes biophotonics has had in Medicine and new opportunities. Devices including Laser Scribing, OCT, Refractive Lasers, and Femtosecond Laser-Assisted Cataract Surgery have transformed the standard of care in Medicine.

As we look back and to the future, what is next for biophotonics in Medicine? Transformation of aphakic IOLs? COVID-19 detection?

Drug fabrication? Regenerative Medicine? The potential of biophotonics continues to solve many challenging problems in Medicine.

This talk will address these and other relevant topics to biophotonics.

DR. ABDALLA R NASSAR Dr. Abdalla R Nassar is an Associate Research Professor and a department head within the Materials Science Division of the Applied Research Laboratory (ARL) at Penn State. Dr. Nassar also has Graduate Faculty appointments with the Engineering Science and Mechanics Department, the Additive Manufacturing & Design Graduate Program, and the Department of Mechanical Engineering at Penn State. He has worked in the field laser processing of metals for over a decade and specifically focused on laser-based AM of metals over the past eight years. He has led and participated in numerous programs on powder bed fusion and directed energy additive manufacturing. In particular, he has developed software and algorithms related to direct integration of AM processes with computational models, implemented data acquisition and control systems on lab-scale and commercial additive manufacturing equipment, discovered defect-detection strategies, designed advanced thermal management systems utilizing PBFAM, and investigated novel strategies for microstructural control, part build-up, and post-processing methods for AM components. His work has led to over seven patent filings along with several dozen peer-reviewed publications.

Quality Assurance in Laser-Based, Metal Additive Manufacturing: Generation and Detection of Systematics and Stochastic Defects Laser-based powder bed fusion (PBF) and directed energy deposition (DED) additive manufacturing have been embraced by much of the aerospace and defense industry for part production and repair. Unfortunately, there still remains considerable uncertainty regarding the causes and effects of many defects types observed in PBF and DED components. Numerous conditions can lead to the formation of defects (i.e. internal discontinuities or undesirable microstructure) that can negatively affect build and part quality.

Some of these defects are easily attributable to systematic errors (e.g. poor processing parameters or contamination). However, many others appear stochastic in nature, appearing randomly even under ideal processing conditions. Here, we detail recent work seeking to elucidate the mechanisms by which systemic and stochastic defects form and approaches to detecting both types insitu. We illustrate that naturally-occurring, stochastics flaws can be emulated via perturbation of processing conditions and can be sensed via illuminated melt pool imaging and observation of the vapor plume produced above the melt. Similar approaches can also be utilized to detect systematic variations in processing parameters. It is also possible to predict and use feed forward control to avoid many defect types. The presented analyses and methodologies present a path forward for mitigation and detection of both systematic and stochastic defects.

Opening Plenaries KENICHI ISHIKAWA Prof. Kenichi L. Ishikawa received the B.Eng. and M.Eng degrees in nuclear engineering from The University of Tokyo (Japan) in 1992 and 1995, respectively, and the Ph.D. (Dr. rer. nat.) degree in physics from RWTH Aachen University (Germany) in 1998. He is currently a Professor at Department of Nuclear Engineering and Management, Graduate School of Engineering, as well as Research Institute for Photon Science and Laser Technology, The University of Tokyo.

He is concurrently Guest Professor at Osaka University since 2019. He was a Postdoctoral Researcher at CEA-Saclay from 1998 to 2000, a Special Postdoctoral Researcher at RIKEN from 2000 to 2002, an Associate Professor at The University of Tokyo from 2002 to 2008, a Senior Researcher at RIKEN from 2008 to 2009, and a Project Associate Professor at The University of Tokyo from 2009 to 2014.

He is internationally renowned for his contributions to numerical calculation and theoretical modeling of laser-matter interaction, ranging from strong-field physics, ultrafast laser science, attosecond science to laser processing. He is currently participating several national projects of Japan to promote smart laser manufacturing and, in particular, leading a nation-wide network project for proposing the optimal processing parameters using artificial intelligence and simulation in cyberspace. He is currently a member of The Engineering Academy of Japan (EAJ), The Japan Society of Applied Physics (JSAP), The Physical Society of Japan (JPS), The Laser Society of Japan (LSJ), Atomic Energy Society of Japan (AESJ), OSA, APS, and SPIE among others.

Building Science and Theory for Smart Laser Manufacturing For a brighter future of the global society, Japan is committed to achieving sustainable growth and becoming a pioneer in the establishment of a new social model Society 5.0. Society 5.0 is defined as a human-centered society that balances economic advancement with the resolution of social problems by a system that highly integrates cyberspace and physical space, i.e., cyberphysical system (CPS). To promote smart production and eventually realize Society 5.0 and sustainable development goals, we develop CPS laser manufacturing capable of proposing the optimal processing parameters using artificial intelligence and numerical calculations based on the science and theory of laser processing combined with massive data of high quality.

Understanding laser processing belongs to multiscale and multidisciplinary cutting-edge science. For example, how atoms, molecules, and materials behave under intense laser irradiation is at the forefront of atomic, molecular, optical, and condensedmatter physics, involving highly nonlinear, dynamical processes. One of our focuses is to understand and simulate such strong laser matter interaction by combining different techniques, even starting from the first principles of quantum mechanics.

We are developing various new methods to accurately calculate the laser-driven electron dynamics and energy transfer from laser to electrons. Also, combining first-principles and molecular dynamics calculations, we start to quantitatively reproduce how atoms are ejected from a laser-irradiated surface. In the macroscopic scale, for instance, we study multiphysics modeling of complex thermal multiphase flows with phase change. We build a nation-wide collaboration network of theoreticians as well as experimentalists that develop, e.g., cutting-edge operando measurement techniques such as high-speed photography and angle-resolved photoemission spectroscopy.

Micro Track Summary Track Co-Chairs DR. CONSTANTIN HAEFNER

Fraunhofer Institute for Laser Technology Aachen, Germany

Dr. Constantin Haefner recently joined the Fraunhofer Institute for Laser Technology (ILT) in Aachen, Germany, as the organization’s executive director. ILT is one of the premier laser R&D institutions in Europe. He oversees more than 500 employees focused on activities such as the development of new laser beam sources, components, and industrial laser processes. Prior, Haefner directed the Advanced Photon Technologies Program at Lawrence Livermore National Laboratory, USA, where he led the development of high-energy cutting-edge laser systems relevant to scientific research and commercial applications. Haefner and his team pushed the frontiers in developing next generation high peak-power lasers – technologies that are now starting to revolutionize the field. Haefner received his Physics Diploma degree from the University of Constance (1999), and his Ph.D. from the University of Heidelberg, Germany (2003). In 2004 he became Research Assistant Professor and Chief Laser Scientist at the University of Nevada Reno’s Nevada Terawatt Facility. In 2006 he joined LLNL where he has since led the R&D of advanced laser technologies.

Haefner won several awards and was elected 2017 to Fellow of OSA for his pioneering work in development of next-generation, high-average-power petawatt laser systems and sustained advancement of state-of-the art laser technologies.

DR. JOHN LOPEZ

University of Bordeaux Bordeaux, France

John Lopez was awarded from the French graduate school of Physics and Chemistry of Bordeaux in 1993. He got his PhD on laser ablation of polymers at the University of Bordeaux in 1997. He has a permanent position as a senior research engineer in the French CNRS since 2001 and he is currently working in a public institute in the UNIVERSITY OF BORDEAUX (CELIA laboratory). He is known worldwide as an expert in laser ablation and laser micro machining. His current research topics are metals and transparent material processing, GHz-burst material processing, beam shaping and laser-assisted eye surgery. John Lopez is the author of nearly 30 peerreviewed scientific papers and 90 proceedings. Furthermore, John Lopez is the President of the French association of industrial laser users called Club Lasers et Procédés since 2010 (CLP); as such he is the general chair of Laser Processing for industry conference (PLI).

He is as well involved as an expert ALPhANOV technology center and on the board of PHOTONICS FRANCE. He was highly involved in the creation of ALPhANOV in 2007 and he used to be the Laser Material Processing Business Unit manager in ALPhANOV from 2007 to 2011. He is also a founding member of the French national committee for laser safety.

Finally, John Lopez was a member of the LIA Board of Directors from 2017 to 2019.

“Laser microprocessing is at the heart of modern manufacturing. The ICALEO 2020 Micro-track conference will cover a wide field of applications such as e-mobility, microelectronics, photovoltaics, medical devices, and aircraft industries. The conference will offer an overview of the latest innovations in the areas of laser technologies, beam shaping and laser material micro processing. Sessions are organized by contributions and advances in processing with respect to wavelength (blue or green lasers), high power ultrafast laser ablation, GHz-burst ultrafast lasers, multibeam or non-diffractive beams, temporal pulse modulation, non-metal materials such as silicon, dielectrics, polymers or CMC composite materials, and hybrid approaches such as laser assisted electrospray deposition or flexible printing. Key contributions were recognized by an optional and voluntary peer-review process and are highlighted in the program.

Unfortunately COVID19 forces this meeting in the virtual conference room and we are saddened not having the opportunity to meet in person. However, to keep scientific exchange and discourse going, the basis of innovation and technology advancement, it is of utmost importance to get together at least digitally and discuss the latest achievements. We have assembled a strong and interesting program in the ICALEO Micro-track. Discussions and Q&A after the presentations, as well as personal exchanges are of essence to this meeting. We are looking forward to meeting at the ICALEO digital venue.”

DR. KOJI SUGIOKA

RIKEN Japan

Koji Sugioka is a Team Leader of Advanced Laser Processing Research Team at RIKEN Center for Advanced Photonics. He received B.E., M.E. and Ph.D. degrees in electronics from Waseda University in 1984, 1986 and 1993, respectively. He was awarded the degree of Doctor Honoris Causa from University of Szeged, Hungary in 2018. Sugioka joined RIKEN in 1986. At RIKEN, he has made important contributions to both fundamental researches on laser-matter interactions and diverse applications including practical use in the said area. He is internationally renowned for his works on laser doping, laser etching, laser surface modification, laser-induced selective metallization, microfabrication of transparent materials, VUV laser processing, laser surface nano-structuring, and 3D micro and nano fabrication. In particular, he is known as a leading scientist in the ultrafast laser processing technology. His current research interests include ultrafast laser processing for microfluidic, optofluidic, microelectronic and optoelectronic applications. Sugioka is currently a member of the board of directors of the Laser Institute of America (LIA), Japanese Laser Processing Society (JLPS) and The Japan Society of Laser Technology (JSTL), a council member of the Intl. Academy of Photonics and Laser Engineering (IAPLE), and a Fellow of SPIE, OSA, LIA, and IAPLE. He is also an editor-in-chief of the Journal of the Laser Micro/Nanoengineering (JLMN) and an editor of Opto-Electronic Advances (OEA), Nanomaterials, Advanced Optical Technology (AOT), and Int. J. Extreme Manufacturing (IJEM).

“Owing to unprecedented advantages including environmental friendliness, decent fabrication efficiency, broad coverage of materials, versatility of processing types, and flexibility in terms of geometry, laser nanomanufacturing has emerged as an efficient tool for producing both nanostructures and nanomaterials as spurred by the inexhaustible new findings in the sophisticated interaction of light fields with matters. The Laser Nanomanufacturing Track of ICALEO 2020 is intended to provide deep insight of the latest achievements in the fields of laser nanofabrication and nanoengineering for creation of novel nanostructures and nanomaterials. The topics of the conference include fundamental physics of laser nanoprocessing, nanomaterial characterization/synthesis, 2D and 3D nanoprocessing, tailored nanomanufacturing, nanopatterning, advanced surface nanostructuring, applications of nanomanufacturing, etc.

Some of the remarkable achievements in recent years from this vibrant field are highlighted as follows. The conference will begin with an invited presentation given by Dr. Shunsuke Inoue from Kyoto University, who will report measurements of fs-laser-induced plasma waves by laser-accelerated electron pulses.

The spatial distribution of electric fields has been measured using electron pulses as the backlight at a temporal resolution of hundreds of femtosecond. Then Dr. Pengyu Yuan from Lawrence Berkeley National Laboratory will present a new energy transport state resolved Raman technique for efficient and accurate characterizations of the thermal and electrical properties of 2D materials by constructing two steady heat conduction states with different laser spot sizes.

Moving to 3D nanomanufacturing, Prof. Yongfeng Lu from University of Nebraska Lincoln will speak about the fabrication of low-density 3D millimeter-scale plasma lenses with submicron resolutions through two-photon polymerization processes. Prof. Godai Miyaji from Tokyo University of Agriculture and Technology will demonstrate the self-organization process of nanostructuring which can be regulated to fabricate a homogeneous nanograting on the target surface in air. Then an optical-field-assisted laser processing (OFLP) technique working as a flexible photo-thermal post-writing technology for mass-customization of dielectric metasurfaces will be introduced by Dr. Xiaolong Zhu from Technical University of Denmark. This technology can fabricate laser-printed dielectric color metasurfaces with a printing resolution up to 127,000 DPI. Laser nanomanufacturing can also be used for optical metasurfaces. Prof. Xinbin Cheng from Tongji University will discuss multilayer metasurfaces exhibiting abnormal reflection with an overview of potential applications for laser systems.”

Prof. Mazumder has received numerous awards including, Bruce Chalmers Award, M. Eugene Merchant Manufacturing Medal, Distinguished University Innovator Award, William T. Ennor Award, and the Arthur L. Schawlow Award. He is a Fellow of the American Society of Mechanical Engineers (ASME), American Society of Metals (ASM), International Academy of Photonics and Laser Engineering, and Laser institute of America (LIA). He is also a former president of LIA.

Metallic Additive Manufacturing: Past, Present, and Future Economist Magazine hailed Additive Manufacturing (AM) as the “third industrial revolution”. AM also features prominently in Factory 4.0. It has been practiced in one form or other for more than 5000 years. A pyramid in Egypt was built at 2800 BC using layer-by-layer construction. Modern versions for this technology are around for almost three decades. The first patent on steriolithography was issued in 1986 to Charles Hull. In many ways it is “back to the future”.

Presently, there are several 3-D printing machine manufacturers using a wide range of raw materials from wax to metals, using various techniques.

They are also making products from food to fashion. Even AM machines capable of remote manufacturing are now possible.

However, one of the critical needs is “certify as you build”. Due to relatively low volume production, conventional statistical quality control is difficult.

In-situ diagnostics and quality assurance is needed and that is a relatively unexplored field. In-situ optical diagnostics and its capability to integrate with process control is a prudent alternative. New optical sensors are being developed to control product health and geometry using imaging, cooling rate by monitoring temperature, microstructure and composition using optical spectra. Ultimately these sensors will enable one to “certify as you build”. Recently the author and his group have developed a technique to analyze the plasma spectra to predict the solid-state phase transformation, which opens up a new horizon for materials processing and manufacturing.

Mathematical model developed for the process includes most of the physics but needs substantial computing time. An effort needs to be made to develop surrogate models, which can converge within 10ms to enable the process control. Flexibility of the process is enormous and essentially it is an enabling technology to materialize many a design. Conceptually one can sit in Santa Fe and fabricate in Sheffield. This paper provides an overview of the past history, present status, and future needs and potential.

DR. NINA LOUISE LANZA Dr. Nina Louise Lanza is the Team Lead for Space and Planetary Exploration in Space and Remote Sensing (ISR-2) at Los Alamos National Laboratory. She is on the science teams for the ChemCam instrument onboard the NASA Curiosity rover and the SuperCam instrument onboard the Perseverance rover. Her current research focuses on understanding the origin and nature of manganese minerals on Mars and how they may serve as potential biosignatures. In addition to her research on Mars, Dr. Lanza spent the 2015-2016 austral summer in Antarctica recovering meteorites with the Antarctic Search for Meteorites project. She is also a regular contributor on the television series How the Universe Works (The Science Channel).

She is thrilled to be living her childhood dream of working on a spaceship.

Using Laser-Based Analysis Techniques on Mars With The ChemCam and SuperCam Instruments The NASA Curiosity rover has been exploring the surface of Mars for the past eight years, carrying with it the ChemCam instrument as part of its scientific payload. ChemCam is a suite of instruments that includes a laser-induced breakdown spectroscopy (LIBS) instrument, which provides chemistry information about geologic materials at standoff distances of up to 7 m from the rover. The ChemCam LIBS instrument has produced over 800,000 individual spectra, an unprecedented number of observations from a single instrument on Mars. With these and other instrument data, we have learned that Curiosity’s landing site in Gale crater once hosted a long-lived freshwater lake that was habitable. As Curiosity continues to produce ever more data, a new NASA Mars rover was recently launched, with a landing date of February 18, 2021. Called Perseverance, this new rover has an all-new science instrument payload, including the SuperCam instrument suite. SuperCam uses a combined LIBS-Raman laser instrument to analyze geologic materials, which allows for direct measurement of both chemistry and mineralogy, thereby uniquely identifying geologic materials.

SuperCam also includes a microphone that can record the sound of LIBS acoustic signals, which provides additional information about the material properties of martian rocks. In this talk, I will describe our two instruments, give an overview of current results from ChemCam and the Curiosity mission, and discuss the goals for the soon-to-land Perseverance mission.
