Abstract: | An efficient source of all-solid-state broadly tunable mid-infrared optical parametric oscillator based on a periodically
poled MgO-doped lithium niobate is reported. The pump source is a 1064nm acousto-optically Q-switched diode-pumped Nd:YAG
laser. A broadly tunable mid-infrared output from 1.56 to 1.67 μm were generated, with corresponding idler wavelengths of
3.34 to 2.93 μm by temperature tuning from 40 to 200°C. When the average pump power is 1.61 W with about 70 ns pulse duration
operating at a repetition rate of 10 kHz, the maximum signal output power of the PPMgLN-OPO is about 211 mW at 1631 nm. |
