Paper Abstract

A novel design for a quasi-three level, microchip high-power laser is proposed. The design uses a Yb:YAG core surrounded by an undoped YAG region of slab shape that could be pumped from one or from both slab sides. Theoretical descriptions of the pumping optimization, pump-beam distribution, and output-to-input power characteristics are presented. The simulations show that from a composite Yb:YAG chip, which consists of a Yb:YAG core of 2.0-mm diameter and 13.0-at.% Yb concentration surrounded by an undoped YAG slab of 5.0-mm width and 0.8-mm thickness, a TEM00 output beam of 100 W continuous-wave power could be obtained. The expected optical-to-optical efficiency is 39%.
