Abstract

In order to obtain a good beam quality from a high power, high repetition rate Q-switched Nd:YAG laser, a complete understanding of the thermally induced birefringence is necessary. We advanced a method by using a computer to simulate the photoelastic effects inside the Nd:YAG working material and developed a set of graphs on thermally induced birefringence via different electrical input power (e.g., 1, 2, 3, 4 kW) and different values in (e.g., 3, 4, 5, 6 mm) diameter of the YAG rod. The simulated results indicate the optimum way of thermal birefringence compensation under different pumping and cooling conditions.
