More info

Lithium Indium Sulfide (LIS) Crystal exhibits nonlinear optical properties similar to those of AgGaS2 and AgGaSe2 crystals but with a distinct crystal structure. As a pyroelectric material, LiInS2 also possesses electro-optic parameters that make it an excellent choice for electro-optic applications. These unique characteristics make LIS crystals with potential for use in a variety of nonlinear optical and electro-optic applications, such as frequency conversion and modulation. Heeger Materials (HM) provides high-quality LiInS2 crystals for advanced research and industrial uses.
