Recent advances in efficiency and mounting technology have lead to new sets of parameters for commercially available high power diode lasers (HDL). Still, these advances have to be proven by extensive long-term aging tests (LAT). The results of these give both the safety margin for operating todays HDL as well as hints towards further improvement. By statistical means clear information on reliability...
GaAs-based diode lasers for emission wavelengths between 800 nm and 1060 nm with AlGaAs-cladding and GaInP-waveguide layers were grown by MOVPE. For wavelengths above 940 nm broad area devices with InGaAs QWs show state-of-the-art threshold current densities. Ridge-waveguide lasers fabricated by selective etching achieve 200 mW CW monomode output powers. (In)GaAsP QW-based diode lasers with an emitting...
