| 摘要: |
| 陶瓷激光器在高掺杂、大尺寸和复合结构设计等方面有着特殊的优势，具备实现高能、高光束质量激光器的潜力。研究了上海硅酸盐所提供的新型国产Nd:YAG陶瓷激光材料的激光输出性能，对比了陶瓷激光棒与单晶激光棒的储能特性，通过主动和被动调Q两种方法分别实现了闪灯泵浦陶瓷脉冲激光器，获得了重频1～20Hz可调，单脉冲百毫焦量级的输出，峰值功率近10MW。验证了陶瓷激光介质在高能激光领域的应用，对大能量、短脉冲陶瓷激光器进行了初步的探索和研究。 |

| Abstract: |
| 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. |
