我们研制了一套啁啾钛宝石激光脉冲放大系统，在10Hz重复频率下获得了9.9fs、11mJ的脉冲能量。通过使用特殊设计的部分反射镜和宽带高损伤阈值反射镜，成功地补偿了放大过程中的光谱窄化。这是第一次演示，据我们所知，直接放大的太瓦亚10飞秒脉冲的啁啾脉冲放大系统的钛：蓝宝石激光器。
We have developed a chirped pulse amplification system of Ti:sapphire laser generating a 9.9 fs pulse with a pulse energy of 11 mJ at a repetition rate of 10 Hz. Spectral narrowing during amplification is successfully compensated by using specially designed partial mirrors and broadband high-damage-threshold mirrors. This is the first demonstration, to the best of our knowledge, of the direct amplification of terawatt sub-10-fs pulses in a chirped pulse amplification system of Ti:sapphire laser.
