Ceramic laser, possessing the advantage of polycrystalline inhesion, has the potential to be high-energy and high-light beam quality laser. The current study researched into the performance of domestic Nd:YAG ceramic created by Shanghai institute of ceramics and realized the actively and passively Q-switched ceramic laser side-pumped by flash lamps. The average pulse energy could be above 100mJ and the repeat rate is up to 20Hz. The peak power reaches nearly 10 MW. The research result in the confirmation of ceramic laser in the field of high-energy laser, and a probe in the short pulse ceramic laser with high energy.
