Micromaser spectrum and phase diffusion dynamics / F. Casagrande, A. Ferraro, A. Lulli, R. Bonifacio, E. Solano, H. Walther. - In: JOURNAL OF OPTICS. - ISSN 1464-4266. - 5:4(2003), pp. S459-S466.
Abstract:
We discuss a scheme to relate the phase diffusion dynamics of the
micromaser field to the measured atomic population statistics. This can
allow us to measure the linewidth of the micromaser spectrum and to solve a
relevant decoherence problem in cavity quantum electrodynamics. The main
steps are (i) a suitable preparation of the cavity field state to generate
coherences, (ii) the transfer of information on the dynamics of field
coherences to probe atoms by the action of an external resonant coherent
field and (iii) the derivation of the phase diffusion rate, hence the
micromaser linewidth, from the measured population statistics of the probe
atoms. The method can be applied even in the presence of trapping states,
where peculiar linewidth oscillations are expected for increasing pump rate,
due to the quantum nature of the micromaser field.
