目前，咽嗽脉冲放大（ＣＰＡ技术已成为实现超短超强多ＴＷ乃至ＰＷ激光输出的标准方法．众所周知，ＣＰＡ技术的基本思想就是，来自振荡源的超短光脉冲，在未被放大之前，先用线性脉冲展宽器将其展宽到ｕｓ级线性惆晰脉冲，以实现在多级放大器链中的有效、无损和无畸变能量放
Currently, pharyngeal pulse amplification (CPA technology has become the standard method to achieve ultra-short and super multi-TW and even PW laser output.As we all know, the basic idea of CPA technology is that the ultrashort light pulse from the oscillation source, before being amplified, Extend it to a linear magnitude of the us-level linear pulse with a linear pulse stretcher to achieve efficient, lossless and distortion-free energy in a multistage amplifier chain
