连续波光阴极注入器的驱动激光器研究

摘要

在连续波光阴极注入器的研究中，驱动激光器是一个关键技术，采用连续锁模振荡器的锁模输出作为种子源，用二极管连续泵浦放大，再连续倍频，可以产生符合注入器要求的激光脉冲列作为驱动激光。%The driving laser is very important in the CW-mode photoinjector. According to the requirement of the CW-mode photoinjector, the output of a CW mode-locked laser can be used as the laser seeds, amplified continuously, and frequency-converted to generate the driving laser. The seeding laser is the diode-pumped self mode-locked laser (GE-100), which can be synchronized to the driving signal through timing stabilizer(CLX-100). The repetition rate of laser pulse can be changed from 81.25MHz to 10.16MHz by Pockels'cell, and every laser pulse is continuously amplified for 8 times. After forth harmonic, the laser pulse energy can reach 0.3 μJ at repetition rate of 10.16MHz, and the laser pulse-duration is 5ps.
