Conception of a hybrid type tilted-pulse-front pumping scheme for the generation of high-energy terahertz pulses is presented. The proposed setup is the combination of the conventional setup containing imaging optics and the contact grating. Calculation results for LiNbO3 and LiTaO3 terahertz generator crystals are presented.
Due to the absence of the detrimental three-photon absorption, LiTaO3 is a promising crystal for terahertz generation when pumping with an 800-nm pump wavelength. The nonlinear optical, photorefractive and dielectric (except the bandwidth) properties at the optical and the terahertz wavelength are very similar to those of LiNbO3. The absorption coefficient and refractive index spectra of 1 mol% Mg-doped...
