Abstract :
Optical constants of nonlinear crystals for terahertz generation were measured by terahertz time-domain spectroscopy. Congruent and stoichiometric crystals of lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) were compared in the 0.1-2 THz range. Stoichiometric lithium tantalate (SLT) was estimated as a most promising single crystal to generate efficient THz source in an ordinary polarization direction. In addition, temperature dependent material dispersion for SLT was derived in the THz range.
