The power spectrum of a strong field resonance fluorescence is derived from non-markovian Bloch equations. It is shown that the Mollow spectrum is modified by non-markovian corrections. The main feature of the non-markovian behavior is a nonsymmetric power spectrum even at exact resonance. The magnitude of the non-markovian asymmetry depends on the power of the driving light. © 1979.
