Name: BaGa4S7 (BGS) Crystal: Advanced Nonlinear Optical Material for Mid-IR Applications
Brand: Entrepreneur Badikov D.V.
Availability: InStock

Description

BaGa4S7(BGS) crystals were grown by the Bridgman-Stockbarger method in the laboratory, and its selenium-containing analogue BaGa4Se7(BGSe) was obtained for the first time with dimensions large enough to measure the coefficients of dispersion and refraction, which is a prerequisite for predicting the features of phase interaction. Today we are ready for commercial deliveries of BGS/ BGSe of any size and in any quantity.
