Paper Abstract

This report represents the results of mathematical modeling of thermo-optical distortion in active elements with rectangular section of the laser systems. The thermo-optical distortions (TOD) in slabs are superposition of the two effects: the change of length of beam path; the change of refraction index due to temperature and stress distributions. The very important mechanisms of TOD had been investigated with numerical simulations. (1) The pumping of slabs which results in inhomogeneity of temperature space distribution along the short sides of slabs. (2) The regular inhomogeneity of pumping along the long the sides of slabs that results in S-type bending. (3) The local inhomogeneity of pumping as a result of pumping defect. (4) The slab support influence on the TOD increasing.
