摘要

在数太瓦钛宝石啁啾脉冲放大系统中(极光Ⅱ升级装置), 对多脉冲序列的放大过程进行了详细的实验研究, 获得了多脉冲序列的放大输出. 每一个放大脉冲串中包含有19个独立的飞秒单脉冲, 其相邻间隔为14.8 ns, 对应的重复频率为67. 5 MHz. 脉冲串的总能量约为122 mJ, 各单脉冲能量从20 mJ指数衰减至0.5 mJ, 脉宽约为60 fs, 对应的峰值功率约为10111010 W. 这种脉冲序列在产生长寿命激光等离子体、激光微加工等方面有重要应用前景.

Abstract

An amplified femtosecond pulse sequence is generated in a multi-TW Ti: sapphire chirped pulse amplification system (JG-II facility). The pulse interval of the pulse sequence is 14.8 ns, corresponding to a frequency of 67.5 MHz. The compressed pulse sequence can reach 122 mJ in 19 independent pulses with a pulse width of about 60 fs. The energy of the pulses declines from 20 mJ to 0.5 mJ, corresponding to a peak power from 1011 W to 1010 W. The pulse sequence has important applications in lengthening the lifetime of the laser produced plasma channel in air and in microfabrication.
