| Abstract: | 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. |

| Keywords: | ultrafast electromagnetic radiation pulses (THz radition field) electro optic sampling detection group velocity mismatching dispersive propagation |
