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 stoichiometric LiTaO3 measured by
terahertz time domain spectroscopy are presented. Optimization calculations have been performed, and results for a hybrid-type high-energy terahertz source using LiTaO3 are presented. About 90 % diffraction efficiency is predicted with a practically feasible contact grating.
