Abstract

Basic optical material for any laser system will be active medium, and the value of output energy varies depending on the efficiency of energy accumulated in medium and on the efficiency of energy extraction during amplification. Potassium-barium-aluminum-phosphate glass KGSS-0180/35 doped with Nd³⁺ (3.5x10²⁰ cm^-3) is used in production of large-sized disc and rod active elements for high peak-power laser amplifiers. Such amplifiers need active elements with light aperture up to 400x400 mm. This wide range of neodymium concentration in glasses of the KGSS-0180 type enables one to use them in manufacturing rod active elements of amplifiers.
