Abstract

The attractiveness of bars for industrial applications depends strongly on the reliable high brightness operation. For 9xx bars we report on high filling factor configurations with 200W reliable output power. Our low filling factor devices with output power between 40W and 90W have proven to operate reliably at output power densities of 85mW per 1µm stripe width, showing power wear-out degradation of less than 0.5% per 1000h operation time. For shorter wavelengths we present solutions for 808-880 nm bars. For our 808nm bars we observe power degradation of less than 4% after 8000h hard-pulse life test at 75W output power.
