An intracavity critically phase-matched optical parametric oscillator (OPO) was demonstrated with a LiNbO{sub 3} crystal placed inside the resonator of a diode side-pumped {ital Q}-switched Nd:YAG laser. The OPO acted as a singly resonating cavity on the signal with a threshold below 10 MW/cm{sup 2}. Output energy as high as 640 {mu}J was observed at the idler wavelength of 3.7 {mu}m, which corresponds to a conversion efficiency of 1.8{percent} from diode light to idler light. Tunability over the wavelength range 3.3{endash}4.15 {mu}m was obtained by rotation of the LiNbO{sub 3} crystal. {copyright} {ital 1996 Optical Society of America.}
