- Abstract
A numerical model of pulsed parametric generation in a ring three-mirror optical parametric oscillator (OPO) based on KTiOPO4 (KTP) crystals has been developed. It involves solving a system of coupled truncated equations describing parametric generation in a ring resonator with three crystals using boundary conditions for the field amplitudes and initial conditions corresponding to the level of quantum noise. It is shown the numerical model satisfactorily quantitatively describes the energy, temporal, and spatial characteristics of signal-wave radiation pulses and their dependence on the pump-radiation pulse energy and OPO-resonator parameters under the experimental conditions. Conditions that ensure efficient (efficiency ≥40%) generation of high-power pulses of signal-wave radiation without destruction of the KTP crystals are formulated based on an analysis of the numerical simulation results.
