摘要
通过采用分步傅里叶变换法求解非线性薛定谔方程,模拟了啁啾光脉冲有振幅调制和相位扰动下的自相位调制(SPM)对压缩光脉冲对比度和预脉冲宽度的影响。结果表明:啁啾光脉冲的振幅调制深度和相位扰动深度越大,则压缩后的光脉冲对比度越小;啁啾光脉冲的振幅调制周期和相位扰动周期越小,则压缩光脉冲的预脉冲宽度越大。
Self phase modulation（SPM） plays an important role on the compressed pulse in chirped pulse amplification lasers systems. The influences of the SPM with amplitude modulations and phase perturbations on the compressed pulse is simulated. The simulations show that more amplitude modulations and phase perturbations lead to lower contrast of the compressed pulse, and bigger modulation cycle results in wider pre-pulse width.
