Abstract

The modification of the structure and optical properties of two-layer silver-lead selenide (Ag-PbSe) films because of exposure to laser nanosecond pulses of near-infrared radiation in the scanning mode is considered. The formation of micro-sized fragments and silver nanoparticles as a result of laser irradiation, as well as their effect on the spectral transmission and reflection of the film, has been revealed. It is shown that the presence of a silver layer on a PbSe film is an effective way to improve the optical characteristics of the material, which expands the scope of possible applications of chalcogenide films of this composition.
