Abstract
The output parameters of the most effective system for pumping of solid-state lasers that is based on laser diode arrays are studied. The spatial profile of radiation of specific diode arrays and the differences in the radiation spectra of emitting elements are determined. It is demonstrated that the main reason for the generation of additional modes and the spectral broadening of laser radiation is related to thermal effects resulting from the spatial nonuniformity of radiation of the diode pumping system.
