BGSe (Barium Gallium Selenide) – Laser Crystal – Nonlinear Crystal – Customized Products

BaGa4Se7(Barium Gallium Selenide), referred to as BGSe crystals, belongs to the monoclinic Pc (No. 7) space group, which has a large band gap (2.64 eV), a wide transmission range (0.47~18 μm), large nonlinear effects (d11=24.3 pm/V，d13=20.4 pm/V), moderate birefringence (Δn=0.06@2 μm) and a high laser damage threshold. The BGSe crystals have good growth performance and are easy to obtain large size high quality single crystals suitable for high power output. the BGSe crystals can be pumped by laser of 1~3 μm to produce tunable lasers up to 18 μm in the mid- and far-infrared. Compared with ZnGeP2, BGSe can be pumped by 1 μm laser sources and can be easily prepared for large-aperture devices. BGSe is currently the best nonlinear optical crystal for frequency down-conversion output of midand far-infrared lasers for mature 1 μm lasers.
