Abstract

The technology for manufacturing active elements for high-power (more than 1 kW) Yb3+:YAG disk lasers has been developed. A series of disk active elements with a thickness of 200...400 mu m, a diameter of 8...15 mm, and a Yb3+ concentration of 8...15 at. % has been created. A model of a CW disk laser with an output power of 45 W, an optical efficiency more than 45%, and a pump power density more than 2.5 kW/cm(2) has been made.
