Resonant Optical Parametric Oscillator

In this paper, we demonstrated a continuous-wave intracavity singly resonant optical parametric oscillator based on periodically poled MgO:LiNbO3 (MgO:PPLN) pumped by a diode-pumped Nd:YVO4 laser at 1064 nm. The singly resonant optical parametric oscillator only outputs the idler light as its cavity high reflectivity was coated at the signal light. When the temperature was controlled at 120°C and the grating period set at 30.5 μm for the MgO:PPLN, a maximum idler output power of 1.27 W and central wavelength at 3251 nm were obtained under an incident diode pump power of 12.4 W, corresponding to the conversion efficiency of 10.2%. By changing the temperature and the grating period of MgO:PPLN crystal, widely tunable mid-infrared spectra from 2.95 to 4.16 μm were achieved.

Output Characteristics

We report on output characteristics of the intracavity optical parametric oscillator at the degenerate wavelength of 2.128 μm based on 1-mm-thick PPLN pumped with 1064-nm pulses of a cw-diode-pumped, acousto-optically Q-switched Nd:YAG laser at 10 kHz repetition rate. A stable and high average output power as high as 6 W with a good beam quality of circular shape was attained without photorefractive damage at the crystal temperature of 143°C. We also observed pump-clamping effect with a singly resonant intracavity length of 5 cm and a pump pulse of 70-ns duration.
