Abstract

The ability of the laser crystal to withstand the damaging effects of thermal stresses and strain is an important factor in the design of high power solid state laser systems. To compute these effects, a set of cylindrical coordinates differential equations relating 3-dimensional thermal stresses and strains relevant to a Cr:LiCAF rod was derived. The c-axis of the end-pumped rod was assumed to be perpendicular to the symmetry axis of the cylindrical crystal. Expressions for spatial temperature rise in such a configuration was obtained and the approach of stress calculations was presented.
