Exploration of Nonlinear Optical Features of Ga2S3–La2S3 Glasses for Optoelectronic Applications

Abstract

An opportunity to operate by laser-induced nonlinear optical efficiencies of Ga₂S₃–La₂S₃ glasses doped with Er³⁺ and La³⁺ ions in the visible and near-infrared spectral ranges was explored. The laser-stimulated nonlinear optical properties were studied. The observed laser power and temperature dependences of the laser-stimulated second-harmonic generation and third-harmonic generation confirm the huge role of anharmonic phonon subsystems. Due to an occurrence of local structural distortions, the efficiency of laser nonlinear optical generation has been enhanced. Simultaneous occurrence of the second and third-order nonlinear optical response may indicate on the possibility of multifunctional applications of the investigated glasses in different electronic devices.
