High power SCH-SQW InGaAsP/GaAs laser diodes without DLD-induced sudden mode failures

This paper describes the results of short period life tests of λ=0.81μm SCH-SQW InGaAsP/Gals laser intended for operation as the pumping sources for Solid state YAG:Nd lasers and presents preliminary data on degradation processes under high optical excitation in the corresponding SCH-SQW InGaAsP/GaAs heterostructures
