Abstract
We present operating and lifetest data on 795 and 808 nm bars with aluminum -free active regions. Conductively cooled bars operate reliably at CW power outputs of 40 W, and have high efficiency, low beam divergence, and narrow spectra. Record CW powers of 115 W CW are demonstrated at 795 nm for 30% f ill-factor bars mounted on microchannel coolers. We also review QCW perform ance and lifetime for higher fill-factor bars processed on identical epitax ial material. (C) 1999 Optical Society of America.
