Beyond the Lamb-Dicke limit, this characterization becomes unsuitable: on the one hand, the vibrational degrees of freedom are not strictly thermal and, on the other hand, the decay pro-cess does not follow a single exponential. Instead, the TīmeklisThe resonance fluorescence spectrum of a laser-cooled trapped ion is theoretically studied in the Lamb-Dicke limit. Angular averaged spectrum around the elastic peak and the motional sidebands is calculated. The widths of the sidebands are shown to be given by the cooling rate of the ion in the trap.
