A new form of frequency-selective all-optical heterodyning at the difference frequency of two modulated laser beams, related to stochastic resonance, is reported. A noise-induced enhancement of the heterodyne signal and of the signal-to-noise ratio has been predicted and observed in an all-optical bistable system for the beams at different wavelengths.
