The paper presents the study results of the semiconductor laser active medium temperature effect, that changes in time during its operation, on its output spectral characteristics. Experimental dependences of the diode laser emission spectra on the laser crystal temperature in the range from 296 to 320 K are investigated. Using a heat fluxes computer model the possible reasons were analyzed for the time variation of the laser diode module spectral characteristics with several single emitters that are fixed on the ladder platform. The obtained results can be used for the large-scale laser diode modules design, including a large number of emitters, with high requirements for the output characteristics stability. Thermal fields and isothermal surfaces for a laser diode module with total thermal loads exceeding 30 W are studied.
