Aj. Henderson et al., CONTINUOUS FREQUENCY TUNING OF A CW OPTICAL PARAMETRIC OSCILLATOR THROUGH TUNING OF ITS PUMP SOURCE, Optics letters, 20(9), 1995, pp. 1029-1031
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 a
s a single cavity and is pumped by the second harmonic of a diode-pump
ed Nd:YLF laser. By simultaneously controlling the cavity length of th
e OPO and the frequency of the pump laser, we could scan the output fr
equency of the OPO over a range of 4.5 GHz.
