Abstract
The value of the generated terahertz power limits the major specifications of the THz coherent techniques in imaging and tomography. We report on the effective generation pulse of THz radiation in a nonlinear crystals partially filling the cross section of the rectangular waveguide. The generation of terahertz (THz) radiation in the band 0.1-3 THz via optical rectification of femtosecond laser pulses in LiNbO3, ZnTe, DAST, GaSe nonlinear optical crystals are presented, as well as the results of the numerical calculations for phase-matching.
