“…The questions of heating the YAG:Yb +3 crystal are also of significance in defining the amplification of laser radiation. In connection with this, many papers [12], for instance, study the problems of cooling the plate of garnet with ytterbium. At the same time, the planar amplifier offers a number of special features in the active element design.…”

With allowances made for the saturation of pump radiation absorption, the energy parameters of planar YAG:Yb +3 amplifiers of continuous-wave-radiation and short pulses were determined. The wave-front aberrations resulting from temperature instability in the active medium were estimated. It was shown that saturation of pump radiation absorption presents an important factor affecting the parameters of planar amplifiers, particularly in the case of short pulses.

We have studied thermally induced distortions of a beam in single cubic syngony crystals of all symmetry groups with an anisotropic elastic stiffness tensor. The arithmetic mean and the difference between the thermally induced phase incursions of eigenpolarisations, as well as the angle of incidence of these polarisations, are calculated for a long rod and a thin disk with radial cooling under uniform volume pumping of the active element. The position of the specific crystal orientations unrelated to its symmetry elements is investigated. The effective values of the thermo-optical constant Q in two specific orientations, as well as the thermo-optical constant P in an arbitrary orientation, are found.
