Abstract:

This paper lists the requirements imposed by the designers of powerful high-energy lasers and radiation amplifiers on KGSS 0180 phosphate glasses with various neodymium concentrations, used to manufacture large disk- and rod-shaped active elements. The classical two-stage technology for melting them is described, and a quantitative characterization is given of the extent to which structural water and the neodymium concentration in the glasses affect the maximum achievable luminescence time and quantum yield. A description is given of why inactive absorption of radiation appears at the lasing wavelength and a method for reducing it in the resulting glasses. A method is indicated for reducing the number of inclusions of metallic platinum in the glass, which affect its radiation strength.

Keywords:
