Paper Abstract

The optical characteristic of Nd:YAG ceramic was introduced, and a LD pumped high efficiency Nd:YAG ceramic laser was demonstrated. The laser threshold is 48mW with R=97% output coupler. With 2W LD pumping, 812mW CW laser output at 1064 nm has been obtained, and the corresponding optical-to-optical efficiency is as high as 45.6%. A LD pumped high efficiency high repetition rate A-O Q-switched Nd:YAG ceramic laser was also demonstrated. With a 2W LD pumping, the obtained narrowest pulse width, highest peak power and highest energy per pulse are 16.4ns, 2.46kW and 40.5μJ, respectively. The experimental study about the influence of repetition rate on the performance of A-O Q-switched pulse laser was emphasized, and the experiment results were analyzed and discussed.
