We report smooth and continuous tuning of the single-frequency output from a continuous-wave, doubly resonant optical parametric oscillator (OPO) based on potassium titanyl phosphate. The device is configured as a single cavity and is pumped by the second harmonic of a diode-pumped Nd:YLF laser. By simultaneously controlling the cavity length of the OPO and the frequency of the pump laser, we could scan the output frequency of the OPO over a range of 4.5 GHz.
