Paper Abstract

The general heat conduction equation is solved for the case of variable thermal conductivity and heat desposition. The solution is applied to some cases of interest for understanding the thermal gradients which exist in high average power solid state lasers. The effect of the temperature dependence of the thermal conductivity and the spatial inhomogeneity of the excitation energy on the accuracy of calculating the magnitude of the temperature gradient in a laser rod is considered. The analytical solutions for some cases of interest are presented, as are some specific results.
