The lasing characteristics of extracavity KTP optical parametric oscillators (OPOs) emitting at 1.57 and 2.14 (2.19) {mu}m upon pumping by multimode Nd{sup 3+}:YAG lasers at 1.064 and 1.32 (1.34) {mu}m, respectively, are studied. The thresholds, conversion efficiencies, and divergences of the output radiation for linear and ring OPOs emitting at 1.57 {mu}m are compared. Low thresholds, a high (up to 40%) conversion efficiency, and a low (no greater than 3.5 mrad) divergence of the output radiation were obtained in a three-mirror ring OPO when the pump energy exceeded the threshold by a factor of ten. Emission at 2.14 and 2.19 {mu}m was obtained in a three-mirror ring OPO pumped by Nd{sup 3+}:YAG laser at 1.32 and 1.34 {mu}m, respectively. The OPO lasing parameters are found to be of practical interest. A compact and efficient ring OPO is built for converting radiation from Nd{sup 3+}:YAG lasers to radiation in the 1.5 - 2-{mu}m range.
