Abstract
We estimate thermal aberrations in Cr:CdSe and Cr:ZnSe chalcogenide crystals exposed to continuous-wave electromagnetic radiation at a wavelength of 1907 nm. Using the SIMULIA Abaqus software suite, deformation of such materials during their heating due to absorption of part of the radiation is simulated numerically. On the basis of the obtained results, the focal distances of the lenses induced in crystalline media are calculated by the matrix optics method.
