  We adopt an open quantum systems perspective to calculate the power spectrum
associated with the electric field generated by an atomic dipole moment
undergoing resonant laser-driving. This spectrum has a similar shape to the
usual Mollow spectrum, but also has some distinct features. For sufficiently
strong laser driving, both spectra have a symmetric triplet structure with a
large central peak and two sidebands. However, the relative height of the
sidebands to the central peak differs in each case. The two spectra also behave
quite differently when the laser Rabi frequency is varied. Both spectra may be
of interest in high-precision experiments into the quantum physics of atomic
systems, especially artificial atoms.
