Abstract

We present a novel approach to the numerical modelling of pulsed nanosecond optical parametric oscillators (OPO’s). Our model expands upon a recent procedure [1] to consider the case of a nondegenerate, singly resonant OPO. A single partial differential equation describes the temporal and transverse variations of the resonated signal field and also accounts for diffraction, phase mis-matching and idler absorption. The pump and idler fields are reconstructed from the signal dynamics. The numerical integration of our single equation model is considerably faster than that of the corresponding three coupled equations.
