The emission spectrum of the bichromatically excited resonance fluorescence of a single atomic particle, i.e. of a permanently trapped and cooled Ba + ion has been recorded. It shows up to five peaks, two of them partially resolved, in agreement with fluorescence spectra of three-level atoms calculated from sets of parameters separately measured from recorded excitation spectra of the integrated fluorescence.

Resonance fluorescence of a single trapped ion is spectrally analyzed using a heterodyne technique. Motional sidebands due to the oscillation of the ion in the harmonic trap potential are observed in the fluorescence spectrum. From the width of the sidebands the cooling rate is obtained and found to be in agreement with the theoretical prediction.
