摘要

分析了二次谐波产生技术在超短光脉冲宽度测量中的应用，详细确定了在考虑不同脉冲形状时，基频场和二次谐波场之间的群速度失配(G\TM)的影响。我们发现，对于干涉自相关和强度自相关，GVM对不同的脉冲形状有不同的影响。

Effect of Group Velocity Mismatch on Second Harmonic Autocorrelation Considering Different Pulse Shapes

The use of second harmonic generation as a technique for ultrashort optic pulse width measurement is analyzed to determine in detail the effect of group velocity mismatch (G\TM) between fundamental and second harmonic fields when considering different pulse shapes. We find that for interferometric autocorrelation and intensity autocorrelation, GVM has different effects versus different pulseshapes.
