2025 Siegman International School on Lasers
28 July - 01 August 2025
Yerevan State University
Yerevan, ARMENIA
The Siegman International School is a week-long program that exposes students to in-depth learning of lasers and their applications from internationally recognized academic and industry leaders in the field.
The Siegman International School on Lasers covers all aspects of lasers and photonics. Each summer up to 100 graduate students are invited to participate in a week-long program to learn from pioneering laser researchers and experts from leading laser companies, highly-regarded professors and fellow students. Attendees are asked to present their own research, which provides valuable experience in building exposure for their work all while building lifelong colleagues and friends.
Anthony Siegman, after whom the school is named, was a past Optica president and member for 50 years. He prioritized not only technological advancements but also creating opportunities for learning and growth among students and future generations.
IPG Photonics partnered with the Optica Foundation and donors around the world to endow this program.
