Annotation
The experimental results of observation of frequency spectra of high-power semiconductor lasers are presented. The reasons for the transformation of laser spectra during long-term time operation are discussed. Estimates of changes in the optical parameters of the laser, which change during its slow degradation and determine the type of its frequency spectrum, are given.
