A periodically poled lithium niobate optical parametric oscillator pumped by a Tm:YAG laser at 2.0124-mum wavelength has been demonstrated. A pump pulse energy of 5.1 mJ generated 0.65 mJ of signal and idler pulse energy at a 50-Hz repetition frequency with a 27.8-mum domain-period-length grating. The lithium niobate crystal at a temperature of 180 degrees C yielded 3.61- and 4.55-mum signal and idler wavelengths, respectively. Wavelength tuning over a wide range was achieved with domain-period lengths from 25.5 to 28.2 mum and crystal temperature tuning from 50 to 180 degrees C. Signal wavelengths of 3.26-3.76 mum and idler wavelengths of 4.33-5.34 mum were generated.
