The LIA, co-chairs and I are delighted to welcome you to the International Congress on Applications of Lasers & Electro-Optics (ICALEO), which will return to the sunny city of Orlando, FL! After two years of an online event, we hope that this year we will meet you again in person.

The conference chairs and program committee are putting together a highly interesting program consisting of presentations and posters from participants from all over the world, which is devoted to four (4) core technical tracks:

Laser Additive Manufacturing

Laser Macroprocessing

Laser Microprocessing

Frontiers in Laser Applications

We are looking forward to an excellent scientific and technical conference in which many presentations and posters will be peer reviewed. This will be combined with the newest developments directly from the industry regarding laser sources, process monitoring and processing strategies ensuring ICALEO will providing an outstanding opportunity to learn about advances in laser material processing.

This year’s ICALEO will again give you the chance to have interesting discussions with researchers, engineers and scientists in a great social atmosphere and the possibility of igniting new projects, new co-operations, or paving the way for new business connections. You will have several opportunities to meet the other attendees and to visit our vendor reception and tabletop display.

I do wish you a very pleasant and rewarding participation in ICALEO and am delighted to welcome you to Orlando in person!
