Several Theoretical Problems in the Measurements of Ultrafast Electromagnetic Radiation Pulses with Electro-optic Sampling Detection

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.
