The influence of laser radiation with λ = 530 and 650 nm on the transmission spectra of amorphous GeSex films was studied. The calculated values of pseudo forbidden gap Eg and refractive index n of films. Two types of photo-induced effects in the films have been identified — photobrightening (GeSe5,...
