Continuous frequency tuning of a cw optical parametric oscillator through tuning of its pump source

Angus Henderson, Miles J. Padgett, J. Zhang, W. Sibbett, Malcolm H. Dunn

Abstract

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.
