Abstract: Based on the theory of stimulated polariton scattering, adopting reported experimental conditions that generate tuning terahertz wave utilizing nonlinear optical parametric oscillation as the theoretical analysis model,and taking GaAs, GaP, InP, ZnTe crystals as representatives, the absorption and gain characteristics in zinc blende crystal are calculated, and the output tuning characteristics of terahertz wave are also analyzed. We give detailed analysis of the cavity structure that efficiently outputs terahertz wave, and compare it with the terahertz parametric oscillator composed of MgO: LiNbO3 crystal.
