Abstract: The interaction of femtosecond laser radiation with a wavelength of 1030 nm with chalcogenide glasses of various compositions has been studied. The dependence of the optical transmission of chalcogenide glasses on the pulse energy and frequency has been experimentally established. The compositions of glasses for their use as an optical medium for laser micromachining in the infrared range have been established. It is shown that Ge$_7$Se$_{93}$ glass is the most suitable optical medium for spectral studies of diamond in the near and mid-IR range.

Keywords: direct laser recording, femtosecond laser pulses, chalcogenide glasses, IR optical materials.
