Cutting-edge Research and Applications in Laser Science


The 2019 CLEO Conference & Exhibition concluded with 3,800 registrants, distinguished talks from Nobel Laureates and other notable speakers, an exhibition with 172 companies and 1,722 research and technical presentations.

CLEO is the world’s premier international forum to learn about innovative advances, research and new technologies from the laser science industry. With six days of technical sessions, special symposia, tutorials, short courses, professional advancement courses, business programming, workshops, exhibits and special events, CLEO highlights the latest research, applications and market-ready technologies in all areas of lasers and photonics. 

Visionary Presentations
“CLEO has been amazing with excellent attendance, visionary plenary speakers, a packed technical program including short courses, new workshops and special sessions celebrating diversity that were standing-room only,” said Ben Eggleton, General Co-chair of CLEO. “The mood has been extremely positive, collaborative and progressive. As always the quality of science presented at CLEO is top-notch with a balance of fundamental science and technology, and benefits from excellent representation from thought leaders from academia, industry and national laboratories.”

 For the first time, CLEO featured topical workshops ranging from commercial application for optical frequency combs and universal quantum computing to initiatives to improving diversity in STEM. The CLEO technical program was composed of 27 topic categories on fundamental science, science and innovations, and applications and technology.

“The opportunity to interact with experts in the field, form partnerships and discuss new technologies in lasers and photonics continues to be a huge draw for CLEO attendees,” said Michal Lipson, General Co-chair of CLEO. “The presentations, workshops and keynote programming cover a wide range of emerging trends that will have a significant impact on cutting-edge innovations.”
