description: The given work is devoted to the study of the heating dynamics the active region of semiconductor bars based on AlGaAs / GaAs heterojunction the study of the motion of the redshift peak wavelength of the spectrum and creating the temperature charts of heating. The following tasks were set to solve: 1. Investigation of the radiative parameters of the laser bar in the mode of generation of powerful laser pulses: watt-ampere characteristics, lasing spectra. 2. Construction of temperature maps of heating the active region of the samples. 3. Comparison of the obtained experimental data for various laser structures. In the course of this work, a set of measurements of the optical characteristics of the samples with different structural designs was carried out. All data were processed using the OriginPro 2018 program. Analysis of the experimental plots showed a stable increase in radiation power with an increase in the pump current pulse amplitude, an insignificant effect on the output characteristics of the laser bar with an increase in the operating temperature, and the absence of differences in the heating of the active region of experimental samples. Due to these facts, the conclusions about the high reliability and low temperature sensitivity of the differential quantum efficiency of the researched lasers were reached.
