摘要：

We demonstrate more than 8-W continuous-wave output power with good beam quality ( M-2 <1.8) from an optically pumped semiconductor disk laser. The combination of low threshold density of 470 W/cm(2) 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. (C) 2003 American Institute of Physics.
