Simulation of parametric oscillation in the submillimeter range at pumping of the ZnGeP2 crystal by a train of 100-ps high-power pulses

Analysis is given for a possibility of singly resonant parametric oscillation in the submillimeter range at synchronous pumping of the ZnGeP2 crystal by a train of 100-ps second-harmonic pulses from the CO2 laser with the radiation energy 1.0 J. The calculation shows that using the ZnGeP2 crystal and the second harmonic of the CO2 laser with the energy density 1.8 J cm(-2), one can get the peak submillimeter radiation power from 3.6 to 12 MW in the range from 95 to 300 A mu m (1.0-3.3 THz). The expected peak power values are larger than the experimental ones obtained by other nonlinear optics methods.
