摘要/Abstract

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E_m(t)的函数关系.并对THz辐射场与飞秒(fs)探测光束在同一介质内传播时的群速度失配以及辐射场自身色散效应的影响作了分析.

关键词: 超快电磁辐射脉冲(THz辐射场), 电光采样测量, 色散效应, 群速度失配

Abstract: This paper discusses the relationship between ultrafast electromagnetic radiation pulses E₀ (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.

Key words: ultrafast electromagnetic radiation pulses (THz radition field), dispersive propagation, electro-optic sampling detection, group-velocity-mismatching
