A simple technique to achieve active cavity-length stabilisation in a synchronously pumped optical parametric oscillator

The dependence of oscillation wavelength on cavity length in a synchronously pumped optical parametric oscillator provides the basis of a scheme for stabilisation of the cavity length and wavelength. The design and performance of a simple implementation of this scheme via the use of a position-sensitive detector is reported for a lithium triborate optical parametric oscillator. The stabilisation scheme has proved effective over the entire tuning range of the oscillator (0.65 - 2.65µm), giving stability against fluctuations up to 200 Hz, with greatly improved amplitude stability, and allowing smooth wavelength tuning over a signal range of ~5nm.
