description: The work is devoted to the study of the influence of waveguide design on the overheating of end-semiconductor lasers. The aim of the work was to measure overheating of lasers at constant current pumping, for this purpose structures with different waveguide designs were selected, a detailed methodology for creating temperature sensors to measure the heating of the upper surface of lasers was developed, these sensors were assembled, an installation for measurements was created. To determine the characteristics of these lasers, measurements were carried out in pulsed mode, the watt-ampere characteristics and radiation spectrum were obtained. To process the results, we used the application program Origin, in which we plotted these characteristics, as well as overheating as a function of pumping current. The results of this work allow us to conclude that in order to increase the output power of the laser, it is worth creating structures with the lowest thermal resistance. This work is valuable because not much research has been done in this direction.
