We address the power scaling issue in end-pumped laser rod amplifiers by studying, experimentally and numerically, the magnitude of thermal lensing in a high-energy diode-pumped Yb:YAG crystal. The spatio-temporal temperature profile of the gain medium and the focal length of the induced thermal lens are determined numerically. The influence of the repetition rate and pumping power on the temperature distribution is analyzed. Experimental measurements covered repetition rates between 1 and 10 Hz and up to 4 kW pumping power.

By using laser-diode as pumping source, a passively Q-switched Nd:YVO4laser with Cr4+:YAG saturable absorber is realized. Considering the Gaussian distribution of the pump beam and the oscillating laser intensity, the coupled rate equations of a LD-pumped passively Q-switched laser with Cr4+:YAG saturable absorber are given. The relations between the pulse width and the pump beam radius in the gain medium as well as the laser beam radius in the saturabe absorber are obtained from the numerical solutions of rate equations, and the theoretical calculations agree with the experimental results.
