摘要:Stimulated polariton scattering (SPS) is one of the most important non-collinear phase-matching nonlinear process. In SPS, the angle between the THz and pump waves is as large as 65 degrees, so it is necessary to study the spatial intensity distributions of the pump, Stokes and THz waves effected by the non-collinear phase-matching. In this work, we take the injection-seeded terahertz wave parametric generator (is-TPG) as an example to obtain the numerical solutions of the coupled-wave equations. The simulation results are focused on the spatial-temporal intensity distributions and the energy input-output characteristics. It is notable that the spatial intensity distributions of the pump and Stokes beams along the THz-wave propagation direction are not uniform as the inputs. The pump wave is depleted along the THz-wave propagation direction while the Stokes wave is increasing at the same time.
