Abstract

We have constructed a numerical model for injection-seeded terahertz-wave parametric generators in which the pump depletion, the duration of the pump pulse, as well as the spatial modes of the pump and seed beams are taken into consideration. Compared with other models which only provide the parametric gain under the assumption of low pump depletion, our model can make the predictions on the energy as well as spatial and temporal profiles of the generated terahertz-wave. Besides, the appropriate value of nonlinear coefficient of MgO:LiNbO3 in terahertz regime is difficult to find in the published works. To solve this problem, Miller’s rule is applied for the wavelength scaling of the nonlinear coefficient during calculation. We present a detailed description of the model and show that its predictions agree well with the reported experimental results. The presented model allows the performance to be estimated when designing an injection-seeded terahertz-wave parametric generator.
