We describe a synchronously pumped femtosecond optical parametric oscillator based on periodically poled LiNbO3 that is broadly tunable in the mid infrared. A transmission window of periodically poled lithium niobate beyond the conventionally accepted infrared absorption edge of 5.4 μm has been exploited to produce idler pulses that are tunable across a wavelength range of 4 μm , with milliwatt-level output powers at wavelengths as long as 6.8 μm . We also present experimental tuning results that are in good agreement with the theoretical phase matching predicted from published infrared-corrected Sellmeier equations for LiNbO3 .
