  • Abstract
    The far-infrared properties of a newly grown crystal, BaGa4Se7, were investigated with a THz-TDS system. Refractive indices and absorption coefficients of this material between 0.1THz-1THz were obtained. The measured properties predicts potential application of BaGa4Se7 in THz-DFG. THz-DFG using BaGa4Se7 was analyzed theoretically and the phase-matching conditions were calculated. It seems that a promising prospect of THz application can be expected by using BaGa4Se7 as the NLO crystal.
