Electro-Optic Sampling was invented by Valdmanis and Mourou in the early 1980’s [8][5]. Its is based on polarization rotation of a short laser pulse when propagating in a medium showing a linear electro-optic effect. The polarization rotation is due to an applied electric filed, i.e. the optical pulse samples the instantaneous electric field, see Fig.11.6

In Figure 11.6 a electic transient is generated with a photo-conductive switch activated by a femtosecond laser pulse. A delayed pulse samples the transient electronic pulse with an electro-optic probe as shown in Figure 11.7.

Figure 11.8 shows an overal version of an electro-optic sampling system according to J. Whitaker, Univ. of Michigan [6]
