The power spectrum of the atomic dipole moment    [PDF]

Adam Stokes, Almut Beige

This paper calculates the power spectrum S(omega) of the electric field generated by the atomic dipole moment of a laser-driven two-level system from an open quantum systems perspective. Its shape is similar to the shape of Mollow's resonance fluorescence spectrum but there are some differences. For sufficiently strong laser driving, there are two sidebands but their relative height is reduced. Moreover, the amplitude of this spectrum has a different dependence on the laser Rabi frequency Omega. It does not vanish when Omega tends to zero. The calculation of the spectrum which we present here involves less approximations than the calculation of Mollow's spectrum and constitutes an interesting alternative property.
