摘　　要：文章给出并采用了光脉冲特性分析新方法,对10 GHz光脉冲在色散平坦光纤中的线性传输前后的时域波形、相位和时间带宽积等作了深入研究,并与数值计算得到的双曲正割和高斯光脉冲线性传输特性作了比较,对光脉冲的时域波形、啁啾等作出了更准确的判断,进一步证实了光脉冲的二次谐波-频率分辨光学门测量及其分析新方法的可靠性和准确性。In this paper, we investigate the temporal waveform, phase, time-bandwidth product of the short pulses （10GHz） before and after their propagations in dispersion-flattened fibers by using a novel method for measuring and analyzing their characteristics, compare them with the linear propagation characteristics of the hyperbolic secant and Gaussian pulses resulted from numerical calculations and evaluate more exactly their temporal waveform and frequency chirp, which further verifies the reliability and accuracy of the new method for the second-harmonic frequency-resolved optical gating.
