Paper Abstract

We report recent results in high power visible diode lasers operating in both the 680 nm band and the 630 nm band. Continuous wave (CW) output powers in excess of 1 W from a 100 p.m aperture and 8.5Wfrom a monolithic 8 mm bar have been obtained in the 680 nm band. At 633 nm, 900 mW have been measured from a 100 jim wide aperture and 3 W from a 1 cm bar. We also discuss the temperature and length dependence of the threshold current density and external efficiency.
