These materials are able to be used as active and passive environments for nano- and femtosecond laser sources. popup.description2  The project plans to study the potential of prustite (Ag3AsS3) and pyrargyrite (Ag3SbS3) doped with f-, p- and d-elements for their use as nonlinear optical materials operating in the infrared range. Optical absorption, photoluminescence, nonlinear optical and photoinduced properties will be widely investigated, and the crystal structure will be established. For the most promising phases, the technology for obtaining large-sized crystals and recommendations for practical use will be developed. Doping affects the physicochemical properties of phases by partially replacing elements and can lead to both significant structural changes and improvement of their physicochemical characteristics. A comprehensive study of these parameters will allow to obtain new, multifunctional materials for optoelectronic technology, which have the prospect of using both active and passive media in the development of triggers that will be controlled by an external optical field, as well as in the design of laser modules, rangefinders, guidance systems in modern military equipment , which work in the infrared spectral range.
