Abstract
A continuous-wave optical power density of 200W/cm(2) is reported for the first time for a 0.1 cm(2) element of a surface emitting GaAs/GaAl As wafer. The laser facets are cleaved on-wafer by a microcleavage tec hnique. The output optical beam is reflected by 45 degrees-integrated beam deflectors situated at a distance of 15 mu m from each laser face t. The lasers were soldered junction-up on a microchannel CuW cooler. The drive current at 20 W CW is 40A with a slope efficiency of 0.7W/A.
