Conventional lasers (from table-top systems to microscopic devices) typically operate in the so-called weak-coupling regime, involving large numbers of atoms and photons; individual quanta have a negligible impact on the system dynamics. However, this is no longer the case when the system approaches the regime of strong coupling for which the number of atoms and photons can become quite small. Indeed, the lasing properties of a single atom in a resonant cavity have been extensively investigated… 

Comparison of Theory and Experiment for a One-Atom Laser in a Regime of Strong Coupling

Our recent paper reports the experimental realization of a one-atom laser in a regime of strong coupling [ J. McKeever, A. Boca, A. D. Boozer, J. R. Buck, and H. J. Kimble, Nature (London) 425, 268

Theory of a single-atom laser including light forces (10 pages)

We study a single incoherently pumped atom moving within an optical high-Q resonator in the strong coupling regime. Using a semiclassical description for the atom and field dynamics, we derive a

The experiments discussed in this thesis focus on the interaction of a single trapped atom with the single mode of a high-finesse optical cavity, in the regime of strong coupling. Chapter 1 gives a

Strong coupling in a single quantum dot–semiconductor microcavity system

The observation of strong coupling of a single two-level solid-state system with a photon, as realized by a single quantum dot in a semiconductor microcavity, may provide a basis for future applications in quantum information processing or schemes for coherent control.

Lasing by driven atoms-cavity system in collective strong coupling regime

This work shows how driven magneto-optically trapped atoms in collective strong coupling regime with the cavity leads to lasing at a frequency red detuned from the atomic transition, which opens up a range of new measurement possibilities with this system.

Observation of strong coupling between one atom and a monolithic microresonator

Strong coupling is achieved, with the rate of coherent coupling exceeding the dissipative rates of the atom and the cavity, and this work opens the way for investigations of optical processes with single atoms and photons in lithographically fabricated microresonators.

Photon properties of light in semiconductor microcavities

Properties of atom-like emitters in cavities are successfully described by cavity quantum electrodynamics (cavity-QED). In this work, we focus on the issue of the steady-state and spectral properties
