AGS (AgGaS2) Nonlinear Crystal
AGS (AgGaS2) Nonlinear Crystal
AgGaS2(AGS) crystal is one of the most effective nonlinear laser crystals used in the infrared working band at present. Because of its large nonlinear coefficient, high infrared transmittance, low optical absorption and scattering, and low wavefront distortion performance, its application in the infrared field has been popularized more and more. At present, this kind of crystal is the best choice for the frequency doubling material of
