Abstract
Continuous-wave 90-W output power is reported from 400-µm thick Yb: YAG/YAG composite structure with 10-at.% Yb: YAG core of 2×2-mm2 area. The slope efficiency and optical-to-optical efficiency with respect to the pump power were 40% and 28%, respectively. Optical phase distortions measurement gives focus shift bellow 0.05 m and shows the absence of astigmatism. Gold-Tin and Indium soldering techniques for bonding the laser crystal to the microchannel cooling system were evaluated.
