A synchronously pumped optical parametric oscillator that is able to deliver a signal pulse at two different wavelengths either simultaneously or even one at a time is presented. As the operation exploits the group-velocity mismatch between the interacting signal and pump pulses, just a cavity-length adjustment is required to switch between the three regimes. The widely tunable signal pulses are shown to be synchronous and near transform limited.
