dc.description.abstract In this paper we report an indirect method based on photomultiplier response calibration to measure the radiant power of the internal second harmonic generation (ISHG) from InGaAs/GaAs/AlGaAs strained single quantum well buried heterostructure laser diodes. We observed enhanced ISHG radiant power, of the order of magnitude of 10-8 W. This phenomenon represents a signature of the beginning of the process of catastrophic optical degradation of the LD mirror facet layers, where the nonlinear optical interaction occurs. en_US
