近年来,超短脉冲激光及其与物质相互作用的研究已发展成为现代物理的一个最前沿领域。提高激光的能量和功率密度以开展强场物理的研究,需采用合适的技术路线进行超短脉冲激光的放大。电子束泵浦KrF激光器口径大、泵浦率高,可直接用于进行超短脉冲激光的放大,一方面可获得高的能量输出,另一方面技术路线简单,解决了传统CPA技术所需的大口径光栅等技术难点,非 In recent years, the research of ultra-short pulse laser and its interaction with matter have become one of the most advanced fields in modern physics. To improve the energy and power density of the laser to carry out the research of strong field physics, it is necessary to amplify the ultrashort pulse laser with appropriate technical route. E-beam pumping KrF laser large caliber, high pump rate, can be directly used for ultrashort pulse laser amplification, on the one hand to obtain high energy output, on the other hand the technical route is simple, to solve the traditional CPA technology required Large aperture grating and other technical difficulties, non
