Abstract
It is shown that a fine and rough structure can be distinguished in the radiation spectrum of a powerful laser diode. The relationship between the spectrum characteristics and the internal parameters of the laser structure was established and experimentally verified, which was observed during the degradation of the device. The effect of losses in the resonator and coherence of laser radiation on both the fine and rough structure of its radiation spectrum is shown.
