The influence of laser radiation at the wavelength of 632.8 nm on the optical properties of ~ 1 µm thick Se (a-Se) glassy films synthesized by vacuum thermal evaporation on quartz substrates has been studied. It is established that an insignificant decrease in their transmittance coefficients (T) and optical gap energy (E_g) is observed after the laser irradiation of the obtained films with a power density of 80 W⋅cm⁻². For the first time, an increase in the reflection coefficient (R) and refractive index (n) of the films was detected in the course of long-term relaxation of their amorphous matrix to a more stable state caused by phase changes in a-Se films. It was established that a significant decrease in transmittance and reflection coefficients, refractive index, and E_g occurs after the laser irradiation of a-Se films with a higher power density (5300 W⋅cm⁻²).

研究了波长为632.8 nm的激光辐射对通过真空热蒸发在石英基板上合成的〜1 µm厚Se（a - Se）玻璃状薄膜的光学性能的影响。它建立一个微不足道的减少他们的透射率系数（Ť）和光隙能量（Ë_克）与80W⋅cm的功率密度所获得的薄膜的激光照射后，观察到^-2。首次在长时间的过程中检测到了薄膜的反射系数（R）和折射率（n）的增加。由于α - Se膜中的相变而使它们的非晶基质松弛到更稳定的状态。已经确定，在以更高的功率密度（5300W·cm ^-2）照射a - Se膜之后，透射率和反射系数，折射率和E _g显着降低。
