Abstract

This study investigates polarization-dependent photoinduced effects in As2 S3 and As2 Se3 thin films excited by fslaser pulses operating in the telecommunications range. The findings demonstrated the localized formation of structural defects, including crystallization, and revealed anisotropyinduced birefringence that varied with laser parameters.
