ABSTRACT
We demonstrate more than 8-W continuous-wave output power with good beam quality (M² <1.8) from an optically pumped semiconductor disk laser. The combination of low threshold density of 470 W/cm² and high differential efficiency of 60% results in an optical-to-optical conversion efficiency of 46% for this high output level. Good epitaxial quality and low thermal resistance allow the scaling of output power with pump spot area.
