为开展超短脉冲激光的研究与应用，中国原子能科学研究院核技术与计算机应用研究所８１室从美国光谱物理公司引进一套ＴＳＡ５０飞秒激光器，目前已完成该系统的调试和验收工作。该系统由多台激光器组成，采用了锁模、啁啾放大等最先进的激光技术，其光路示意图示于图１。采用 In order to carry out the research and application of ultra-short pulse laser, China Institute of Atomic Energy, Room 81, Institute of Nuclear Technology and Computer Application, introduced a set of TSA50 femtosecond laser from American Spectroscopic Physics Company and has completed the commissioning and acceptance of the system. The system consists of multiple lasers, using a mode-locked, chirp amplification and other state-of-the-art laser technology, the optical schematic diagram shown in Figure 1. use
