Abstract

In this paper, we introduce analytical derivations for the thermal lensing of an end-pumped laser disk. These derivations are done for pump beam shapes from Gaussian to top hat, assuming that the thermal conductivity is either constant with the temperature or not. We give examples in two temperature regions, where the thermal conductivity exhibits T 1 or T 2 dependence. Numerical applications are given for a Q-CW pumped Yb:YAG disk laser.
