Abstract :
We studied the parameters that affect terahertz wave generation via optical rectification in nonlinear crystals. We used simulations based on one-dimensional propagation equations of Maxwell in GaAs to consider the effect of these parameters on conversion efficiency. In order to study the effect of nonlinear absorption, we used Drude-model.
