摘要
本文讨论了在考虑不同脉冲形状时群速失配效应对二次谐波自相关法测量超短光脉冲宽度的影响结果表明了脉冲形状不同时。
To use second harmonic generation as a technique for ultrashort optic pulse width measurement is analyzed to determine in detail the effect of group velocity mismatch (GVM) between fundamental and second harmonic fields when considering different pulse shapes It is found that for interferometric autocorrelation and intensity autocorrelation,GVM has different effects versus different pulseshapes
