A high-efficiency extracavity parametric oscillator based on KTP crystals for converting radiation of Nd{sup 3+}: YAG lasers at 1.064 {mu}m to radiation at 1.573 {mu}m is made and its oscillation characteristics are studied. A differential efficiency of 56.5% and a threshold energy density of 0.06 J cm{sup -2} were obtained. The angular divergence of parametric emission did not exceed four diffraction limits in a wide range of pump energies. The feasibility of stable operation for a more than 30-fold excess of pump energy over the threshold value was obtained. (nonlinear optical phenomena and devices)
