We describe a compact all-solid-state continuous-wave, singly resonant optical parametric oscillator (SRO) based on periodically poled RbTiOAsO4. The SRO is pumped at 1.064 µm by a Nd:YVO4laser, which is itself pumped by a 3-W diode laser. Using the intracavity technique produced an oscillation threshold for the SRO of only 1.6 W (diode-laser power). For 3 W of diode pump power some 65 mW was obtained in the (nonresonant) idler (wavelength 3.52µm). Temperature tuning over the range 10–100 °C resulted in tuning ranges of 1.52–1.54 and 3.41–3.54µm for the signal and the idler waves, respectively. Importantly, relaxation oscillations were absent.
