Amplification of UV ultrashort pulse laser in e-beam pumped KrF amplifier
摘要
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.用天光一号电子束泵浦KrF激光器进行超短脉冲激光放大,将超短脉冲激光放大到2~3J、1.2ps, 激光功率达到2TW.测量了石英窗镜中的非线性吸收系数和超短脉冲激光脉宽的变化.
Abstract
Experimental investigations were performed for amplification of ultrashort pulse laser with Heaven I e beam pumped KrF amplifier in CIAE. A 50mJ, 420fs UV ultrashort pulse was amplified to 2-3J energy, 1.2ps pulse duration, and 2TW laser power. Experimental technique such as synchronization were describe, some parameters such as nonlinear absorb coefficient were measured in experiment. As a result, it is possible to achieve ultra strong UV laser wih intensity higher than 10 19 W/cm 2 in recently years.
