- Аннотация: 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 ~1-μm-thick glassy (amorphous) Se films synthesized by vacuum thermal evaporation are reported. It is shown that, depending on the radiation intensity and the exposure time, the laser-induced modification of films is accompanied by different changes in their roughness and by the appearance of structures different in size and the phase composition on the film surface. The formation of submicron-ridge chains on the surface of the laser-modified films yields an increase in their reflectance and refractive index and a decrease in their optical thickness.
