In optically pumped cw edge emitting laser operation, one sample shows a characteristic temperature of with a maximum operation temperature of 170 K which corresponds to the low Auger recombination coefficients and the very good growth quality. In pulsed laser operation mode (@) the maximum operation temperature is 320 K.
The maximum output power obtained is 14 mW (cw) per facet. The differential quantum efficiency is 3.3 % at 80 K.
