Study of Broadband Mid-infrared Optical Parametric Amplification in LiGaS2, LiGaSe2, LiInS2, and LiInSe2 Crystals

Abstract

Phase-matching characteristics and gain spectra of Li-based crystals in type-I arrangement were provided. The signal gain spectrum bandwidths from few hundreds of nanometers to few thousands of nanometers can be obtained.
