915 nm quantum dot lasers with temperature stable emission wavelengths have been realised for uncooled high-power applications. Broad area lasers with optimised dot geometry exhibit a thermal induced wavelength shift of 0.09 nm/K, which is 3.5 times lower than for quantum well lasers. Despite this improvement the lasers show high output powers of more than 3 W and wallplug efficiencies of 55% in continuous-wave operation.
