Computational and experimental studies of the lasing characteristics of IR optical parametric oscillator (OPO) on the nonlinear crystal LiNbO3 were performed. The implemented outside-the-cavity ring scheme OPO with replaceable output mirrors, allows the converting the pump frequency in parametric generation to 30 % over the tuning range from 1,41 to 4,24 microns.
