摘要：
Cascaded optical parametric processes based on periodically poled KTiOPO4 (PPKTP) generating a tunable terahertz (THz) wave are analyzed. The forward and backward cascaded optical parametric processes are theoretically analyzed. Tuning characteristics of the THz wave that relate to the parameters of the pump wavelength and the grating period of PPKTP are numerically simulated. The gain and absorption characteristics of the generating THz wave are deduced in the situation of quasi-phase-matching configuration. The characteristics of PPKTP for THz wave parametric oscillator (TPO) are compared with periodically poled LiNbO3 (PPLN). The analyses indicate that PPKTP is more suitable than PPLN for TPO.
