Abstract
A 2 μm wavelength pumped Optical Parametric Oscillator (OPO) using the new nonlinear material Periodically Poled Lithium Niobate (PPLN) has been demonstrated. The OPO was pumped by a Tm:YAG laser at 2.013 μm wavelength and operated doubly resonant close to degeneracy at 3.8 to 4 pm and 4 to 4.3 μm signal and idler wavelengths respectively. Pumping at 9.2 mJ pulse energy produced a combined signal and idler pulse energy of 0.82 mJ, corresponding to 8.9% efficiency. The experiments showed a difference between calculated and observed domain period length close to degeneracy caused by deviations in the dispersion data for Lithium Niobate in the 3 to 5 μm wavelength range.
