  • Abstract
    Results on effective generation of terahertz (THz) radiation in band 0.1-2.5 THz via optical rectification of femtosecond laser pulses in LiNbO3 plate tapered at the end are presented. It is shown that placing the LiNbO3 crystal in the free space and in the waveguide both the phase-matching and time and spectral features of the emitted THz field are changed.
