Paper Abstract

High power diode lasers are important for a variety of applications including diode-pumped (DP) solid state lasers, DP fiber lasers/amplifiers and a variety of printing and medical applications. Recently, there have been significant advances in the maximum cw powers achieved from both multimode and singlemode lasers in both AlGaAs-based and InGaAsP- based materials. The highest powers from broad area lasers have been achieved with high quality AlGaAs-based materials. For example, cw powers of 11.3 and 16.5 W have been demonstrated at 870 nm from 100 and 200 micrometers wide apertures, respectively. These power levels correspond to a facet loading of 80-110 mW/micrometers and facet power densities of 27 MW/cm2 which are approximately 2-fold higher than previously reported results. In this paper we report on the performance, reliability and degradation characteristics of AlGaAs- based lasers.
