INFRARED NONLINEAR OPTICAL CRYSTAL MATERIAL, METHOD FOR PREPARATION THEREOF, AND APPLICATION THEREOF

摘要

Disclosed are a nonlinear optical crystal material, a method for preparation thereof, and an application thereof. The material has excellent infrared nonlinear optical performance, and its frequency doubling strength (granularity of 50-100 microns) can reach 1-3 times that of AgGaS2 of the same granularity. The powder laser damage threshold of the material can reach 100-260 times that of AgGaS2 of the same granularity, and 1-3 times that of KTiOPO4(KTP) of the same granularity.
