A channeled-substrate-planar AlGaAs laser has been operated to 190 mW cw, and 170 mW cw in single fundamental spatial mode. A single fundamental spectral mode is observed up to about 70 mW. Beyond 70 mW there are minor increases in spectral sideband power and the far-field pattern broadened asymmetrically with increased drive. Both these effects are attributed to spatial ‘‘hole burning.’’
