100 mu m-stripe lasers with a tensile-strained GaAsyP1-y quantum well embed
ded in a low-loss AlGaAs large-optical-cavity structure provide a record-hi
gh CW power of 7W at 735nm from 2mm-long devices. The transverse beam patte
rn has a narrow 25 degrees beamwidth. Reliability tests at the 0.5W CW powe
r level suggest lifetimes > 10(4)h.
