摘　　要：通过对干涉自相关信号包络宽度及超短激光脉冲光谱宽度的分析,得到了干涉自相关曲线宽度与啁啾量值之间、超短激光脉冲光谱宽度与啁啾量值之间的对应关系,并获得了不含啁啾的超短激光脉冲宽度与光谱宽度及干涉自相关宽度之间的变换极限值,以及含有啁啾的超短激光脉冲宽度与光谱宽度及干涉自相关宽度之间的数量关系.Based on a quantitative relationship between chirp value in ultrashort laser pulse and spectral width of ultrashort laser pulses and width of interferometric autocorrelation （IAC） envelope, a transform limit value between width of an unchirped ultrashort laser pulse and width of interferometric autocorrelation （IAC） envelope and spectral width of ultrashort laser pulses was obtained. Furthermore, quantitative relationship between width of an chirped ultrashort laser pulse and width of interferometric autocorrelation （IAC） envelope and spectral width of ultrashort laser pulses was obtained.
