An apparatus and method for achieving a near diffraction-limited, high-average power output from a solid-state laser oscillator are provided. The solid-state laser uses multiple disk-shaped laser gain media having a large optical aperture placed in an unstable resonator. The laser gain media is provided...http://www.google.se/patents/US6888872?utm_source=gb-gplus-sharePatent US6888872 - Solid-state laser oscillator with gain media in active mirror configuration
