摘　　要：讨论普遍情况下超快电磁辐射脉冲 E0 (t) (THz辐射场 )及其电光采样测量值 Em(t)的函数关系 .并对THz辐射场与飞秒 (fs)This paper discusses the relationship between ultrafast electromagnetic radiation pulses E 0(t)(THz radiation field) and the value of electro optic sampling E m(t).The influence of group velocity mismatching on the THz radiation field and fs optical probe pulses and the effects of self dispersive propagation in radiation field are also analysed.
