Abstract

A method is developed to solve the system of shortened equations describing parametric generation in a one-frequency OPO cavity under nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP₂, AgGaSe₂, and HgGa₂S₄ crystals and the optimal reflection coefficient of the output mirror are estimated versus the pump energy density W_p at different values ofthe OPO nonstationarity parameter γ. It is found that for any W_p an optimal value of the pump pulse duration τ_p, exists stipulated by the parametric oscillation threshold. It is concluded that OPO with high (up to tens of watt) output power can be developed.
