OCLA SYMPOSIUM 2024, 16th April 2024

We are pleased to announce that the Symposium on Optical Coatings for Laser Applications OCLA will be organized for the ninth time on April 16th, 2024. This year, RhySearch is hosting the event in Buchs (SG).

Presentations will be given by renowned speakers in the fields of optical coatings, laser technology and LIDT measurement. The event provides an excellent opportunity to foster communication and networking between multidisciplinary industrial and research groups. As a joint organizing committee, Fraunhofer IOF, OST, RhySearch, OptoNet and Swissphotonics look forward to welcoming you to Buchs (SG).

Symposium on Optical Coatings for Laser Applications

Join us at this event where attendees and speakers alike can benefit from a rich network, exchange ideas, and gain insight into new trends, measurement methodologies, and research findings.
