Palmer House Hilton • Chicago, IL

ADVANCE PROGRAM

ICALEO 2023 General Chair Welcome

Klaus Löffler is Managing Director at Precitec GmbH. He graduated from the IFSW University of Stuttgart. Since 1991 he is active in the laser industry starting as a laser development engineer. Many successful industrial laser applications in the industry have been based on his involvement. His driving force is the cooperation between research institutions and industrial end users on a global base to bring ideas into usable products in a fast way. He started his involvement with LIA in 1997 as a longterm member of the Executive Board and Advisory Board and has been President in 2013. He founded the LIA Running Club and is a Fellow of the LIA.

We are excited to host the world’s leading international conference on Lasers and ElectroOptics in Chicago on October 16-19, 2023.

The Laser has been shown to have the potential to revolutionize solutions for major global challenges like energy usage and supply, global warming, and CO2 footprint. Even the fusion energy breakthrough is based on laser technology. The conference, with peer-reviewed scientific and technical presentations, will focus on the newest results in Micro Applications, Macro Applications, Additive Manufacturing, Beam Shaping and Frontiers in Laser Applications. Additionally, the Battery Manufacturing and Artificial Intelligence in Laser Processing Tracks will give you an overview of the process combined with the newest advances in laser application results.

The Business Session will bring the business aspect and environment of the laser to the audience and the possibility to discuss with seasoned industry leaders from around the world.

Due to our great location in Chicago, we will leave the conference room on the last day for a unique experience as we travel to where “industrial lasers” live in three local factories.

Whether this is the first time you are hearing about ICALEO or you are a longtime attendee, you will find something of interest, new ideas, and an excellent opportunity to network with other laser specialists worldwide. Don’t miss this opportunity to meet up with other laser professionals from around the world to learn, share, and make new friends.

You can find registration and more at icaleo.org. The Laser Institute of America Team and I look forward to seeing you in Chicago at ICALEO 2023!

P.S. Don’t forget to join the laser running club, as we start each morning off with a breath of fresh air!
