Abstract :
The generation of terahertz (THz) radiation is demonstrated by using the spatial dispersion of an femtosecond optical pulse. The overlap of two dispersed beams with a spatial shift allows us to generate a narrowband radiation on the basis of photo mixing. Additionally the lateral shift of the beam can tune the frequency of the THz radiation.
