The spectral and the temporal behavior of high-intensity negatively chirped femtosecond pulses in normally dispersive media at different input parameters are experimentally studied. The spectrum of the pulse is reshaped due to strong self-actions. The pulse is self-compressed, instead of broadening, accompanied with the spectral FWHM bandwidth shortened. Steepening of the leading edge of the pulse and spectral red-shift are observed in the experiment. The numerical simulation shows that the result is in agreement with the experimental result.
实验研究了不同输入参数下，高强度负啁啾飞秒脉冲在正常色散介质中的光谱和时间行为。由于强烈的自作用，脉冲光谱发生重塑。脉冲发生自压缩而非展宽，同时光谱半高宽带宽缩短。实验中观察到脉冲前沿变陡和光谱红移现象。数值模拟表明，该结果与实验结果一致。
