| 摘 要： | 介绍了频率分辨光学门法（FROG）回归超短脉冲的测量原理和恢复脉冲的二元相位恢复算法。详细介绍了基于矩阵的广义主元素投影法,对广义投影法和基于矩阵的广义主元素投影法进行了比较,数值模拟了超短脉冲的二次谐波型频率分辨光学门（SHG-FROG）迹线,用两种投影法从迹线中恢复了脉冲的振幅和相位。结果表明,两种方法都能很好地回归超短脉冲,但基于矩阵的广义主元素投影法运算时间短。

| Abstract: | The theory and the algorithm of the frequency-resolved optical gating(FROG) method for retrieving amplitude and phase of ultrashort laser pulse were presented.Generalized Projects(PG) algorithm and Principal Component Generalized Projects(PCGP) algorithm were compared.With Gauss linearly chirped pulse,second harmonic generating frequency-resolved optical gating(SHG-FROG) trace was numerically simulated.Then,the amplitude and the phase of the pulse were retrieved for the free-noise SHG-FROG traces using two ... |
