Abstract

An intracavity critically phase-matched optical parametric oscillator (OPO) was demonstrated with a LiNbO3 crystal placed inside the resonator of a diode side-pumped Q-switched Nd:YAG laser. The OPO acted as a singly resonating cavity on the signal with a threshold below 10 MW/cm2. Output energy as high as 640 μJ was observed at the idler wavelength of 3.7 μm, which corresponds to a conversion efficiency of 1.8% from diode light to idler light. Tunability over the wavelength range 3.3–4.15 μm was obtained by rotation of the LiNbO3 crystal.
