Abstract
We have demonstrated a high-power laser oscillator with end-cooling using a sapphire-sandwiched Yb:YAG disk at near liquid nitrogen temperature. An output power of 74 W with near-diffraction-limited beam was obtained from a 0.8-mm thick active medium. The slope efficiency and the maximum optical-optical efficiency were 77% and 62%, respectively, with respect to absorbed pump power. © 2005 OSA/ASSP 2005.
