GAMDAN Optics Presents Seamless & Scalable Method for Large Aperture LBO

Presentation Detail:

At our presentation at SPIE Defense & Security 2025 and CLEO 2025, we shared the latest updates in our research and testing with Aperture Enlargement of LBO crystals in partnership with LLE (Laboratory for Laser Energetics, Rochester, NY).

Abstract

An optically seamless method for increasing the aperture or length of nonlinear materials has been developed, which is suitable for optics in high energy laser systems and other applications. Differences between aperture and length scaling are analyzed. Bonding of component pairs of a nonlinear crystal, lithium tri-borate, is experimentally demonstrated by GAMDAN Optics Inc. and tested at the Laboratory of Laser Energetics at the University of Rochester. A bonded crystal is shown to deliver beam quality and second harmonic conversion efficiency that is equivalent to that of a monolithic crystal of similar dimensions.
