Non-linear crystal
LiGaS2 / LiGaSe2 / LiGaTe2 Ascut Co.

LGS and LGSe are a very recently proposed IR new nonlinear materials with a wurtzite-type structure and UV transmission down to 0.32, 0.38 µm respectively.
LGT - most effective material of LBC2 crystal group with chalcopyrite structure - is a subject for joint investigations and collaboration.

Crystals of LiBC2 group are characterised by a set of important physical parameters, such as large band gap, low two photon absorption, wide transparency range, including THz window, low group velocity mismatch, high thermal conductivity, low anisotropy of thermal expansion coefficient, etc. which lead to effective use in tunable laser systems in wide spectral range.
