Investigation of nonlinear effects usually requires the use of macroscopic media and intense light fields. The underlying reason for this is, in addition to the inherently weak nature of nonlinear processes, the weak coupling of light and matter. We report on four-wave mixing in a single organic molecule placed at the tight focus of two near resonant laser beams [1]. A weak probe beam is scanned across the molecular resonance, while a strong pump beam is kept at a fixed detuning. By directly monitoring the intensity of the probe beam after the interaction with the molecule, we observe a rich set of resonance profiles in excellent agreement with theoretical calculations. We discuss future experiments aimed at nonlinear studies with few-photon light fields and single quantum emitters.
