© Published under licence by IOP Publishing Ltd.This article presents the results of three-dimensional modeling of thermo-elastic stresses arising during the operation of a powerful laser diode bars mounted on a CuW thermal compensator using AuSn soldering alloy in a wide range of thermal loads up to extreme values. Calculated distributions of thermo-elastic stresses at the output and highly reflective mirror of the laser bar is compared. An interpretation of the results obtained, in particular, higher values of thermo-elastic stresses on a less hot highly reflective mirror, in comparison with a hotter output mirror, is proposed.
