Abstract

Numerical model of two-color short-cavity fiber laser with nonlinear crystal inside the cavity for terahertz generation is proposed. THz field generation is due to down-frequency conversion. Proposed model is based on the transport-type equations, spatial discretization along the cavity axis, and calculation of temporal variations both electric field amplitude and active media inversion at these points.
