Abstract
The design and operation of a pulsed quasi-phase-matched periodically poled lithium niobate optical parametric oscillator in the grazing incidence configuration are described. A narrow bandwidth of 0.3 cm-1 is demonstrated over most of the full tuning range of the device. Broad and rapid scanning has been achieved by rotation of a single mirror. Long-term stable operation and a pump-to-signal power efficiency of 46% are shown to be possible. Methods to improve the bandwidth are discussed.
