BaGa2GeSe6 (Barium Selenium Germanium Gallium) – Laser Crystal – Nonlinear Crystal – Customized Products
BaGa2GeSe6 (Barium Selenium Germanium Gallium), referred to as BGGSe crystal, is a tripartite crystal system R3 space group with high laser damage threshold, wide transmission range (0.5~18μm), moderate birefringence (0.08~0.11), large nonlinear coefficient (d11=23.6 pm/V), stable chemical properties, no tedious post-treatment such as annealing and its surface high chemical stability, no post-growth treatment, high crystal symmetry, and easy processing. Capable of being pumped using Nd: YAG laser, it has important potential for infrared laser frequency conversion such as CO and CO2 laser frequency doubling and optical parametric oscillation to generate mid- and far-infrared lasers. Due to the low dispersion nature and high damage threshold of the BGGSe crystal, it has advantages in ultra-wide mixing and ultra-short pulse output.
