| 摘 要： | 通过数值求解非线性三波耦合方程组，并利用色散致啁啾引起的瞬时频率与时间的关系，模拟了啁啾脉冲在光参量放大过程中的脉冲波形和频谱形状的变化关系，以及通过压缩器的脉冲形状。模拟结果表明：啁啾脉冲在光参量放大过程中的时域宽度和频谱有很小程度的加宽，但基本上不影响放大后脉冲的压缩及信噪比。

| Abstract: | In this paper, the nonlinear coup led equations are presented and the pulse properties of an optical parametric chirped pulse amplification(OPCPA) system are studied. By numerical simulation, it is discovered that signal temporal profiles and spectral profiles broaden after saturated amplification, but the pulse and spectra broadening don't affect the S/N coefficient of the compressed pulse. Analysis and discussions are also given. |
