飞秒光脉冲在透镜和非线性晶体中的展宽

Broadening of Femtosecond Optical Pulse in Lens and Nonlinear Crystal

计算了飞秒光脉冲在具有群速度色散的介质中的展宽,证明在飞秒光脉冲的自相关测量中,由于透镜和非线性晶体的群速度色散所引起的展宽是一个不容忽视的因素。

In this paper, we calculated the broadening value of femtosecond optical pulse ina medium with dispersion. The broadening value from lens and nonlinear crystal(KDP) in theautocorrelator was not negligible.
