The present state of laser glasses production for optoelectronic systems and devices is considered. The limitations of existing laser glasses and the necessity to create new ones have been viewed. The urgency of the development and introduction of new types of laser glass for its use in both civilian and defense equipment sectors is shown. The technological complexity of the phosphate erbium glasses production is substantiated. The purpose of the work is to create laser glasses and make a laser element, will be operating wavelength of 1.54 μm. Optimum concentration of rare earth oxides in laser glasses has been determined. The quality control methodology and technology of laser glasses were developed. The production of a new laser glass makes it possible to use it in modern optoelectronic systems. The laser elements were fabricated and their generation characteristics were investigated. The results of the laser elements industrial testing are presented.

Abstract: In this paper the results of the practical definition of the braking parameter of uranium coating fission fragment in the active laser element of nuclear-pumped laser in a gaseous environment are presented. A description of the experimental method for removing the fission spectra of a NPL uranium coating is given. This method is based on measuring the fission fragments energy spectra emitted from the coating to a gas mixture with the help of a semiconductor detector. To calibrate the fission fragment sensors a californium source the fragments of which have a characteristic spectrum is used. The results of the analysis of the sections of the experimental spectra are presented. On the basis of the findings the theoretical model of the fission energy transfer process in a gaseous environment were checked. As the determining parameters in the modeling of this process, the pressure of the gas mixture in the cuvette with the source and the distance from the fission fragment source to the semiconductor sensors are chosen. The functional dependences of the obtained amplitude spectra on these parameters are determined. A mathematical description of the disperse energy fragment process is presented. The basis of this description is a two-parameter dependence.
