Description

one

The invention relates to the field of quantum electronics devices and can be used to create high-performance high-power solid-state ontic quantum geoerators (JAGs) and amplifiers (OCAs).

There are known lithium-silicon stek.ta, which included the following komonsnty, they say. %:

SiO245-75

AlsOs0-10

LiaO18-35

CaO0,5-30

as well as small amounts of iodine oxide and cerium oxide. However, efficiency solid state laser made on the basis of known glasses is small, and their efficiency is not high enough.

The purpose:., The invention is the creation of active media for solid-state laser systems with high k.n.d. and high mobility.

The goal is achieved by introducing into the lithium-silicon glass one of the alkali metal oxides (Na, K, Rb, Cs) or their mixture in the amount of 0.5-10 mol. % Alkaline earth metal oxides (beryllium, magnesium, strontium) or mixtures thereof may also be present in glass.

Solid state laser systems made on the basis of the proposed material have

and a higher capacity, longer service life, and can accommodate higher concentrations of neodymium than a JAG from known glasses, which can significantly increase the output power of generation.
