Abstract
Abstract The results of studies of the effect of low–power He-Ne laser radiation at a wavelength of 632.8 nm on the surface morphology of glassy (amorphous) Se films with a thickness of ~ 1 µm synthesized by vacuum-thermal evaporation are presented. It is shown that depending on the intensity and time of radiation exposure, laser modification of films is accompanied by various changes in their roughness and the appearance of structures on the surface of the films under study that differ in size and phase composition. The formation of submicron ridge chains on the surfaces of laser-modified films leads to an increase in their reflection coefficient and refraction index and a decrease in their optical thickness.
