摘要

The effect of laser radiation on the formation of fi lm-like deposits on the surface of optical parts located in closed volumes containing sealants such as VGO-1, KLT-30, U-2-28, and K-68 has been studied. X-ray photoelectron spectroscopy and IR spectroscopy were used to determine the composition of the fi lm-like deposits. The composition of the gas medium was determined by mass spectrometry. The formation kinetics of fi lm-like deposits were investigated as a function of the medium temperature and the laser radiation parameters. Possible formation mechanisms of the fi lm-like deposits and methods for their elimination were considered.
