    Optical channeling and laser spectroscopy within a microcavity

    A study of the radiative properties of atoms confined within micron-sized cavities is reported. An experiment undertaken to observe directly by spectroscopy London-van der Waals energy-level shifts, which are closely related to the strong suppression of spontaneous decay from an excited state, is described. This requires that the atoms be confined to a small region compared with the dimensions of the cavity. A technique for obtaining a hypercollimated beam is described. Direct spectroscopy of the level shifts in the confined atoms due to the walls of the cavity is under way.

    New limits on time reversal symmetry violation in thallium fluoride

    Recent results in the search for a T-violating hyperfine interaction of the spin-1/2 thallium nucleus in the molecule thallium fluoride (TIF) are reported. The interaction is of interest because it violates both parity and time reversal invariance and is of a rather general form. To detect the interaction, the hyperfine magnetic resonance frequency of the T1 nucleus (due principally to the spin-rotation coupling) was observed in the presence of strong external electric field E. A tenfold improvement over previous results was obtained, placing new constraints on the electric dipole moment (EDM) of the proton, the EDM of the electron, the T-violating tensor coupling strength of the weak interaction, and the Schiff moment of the T1 nucleus.

    Isotopic effects on quantum jumps in trapped magnesium ions

    , Pages: 242-243

    An ion trapping and laser cooling system suitable for magnesium ions has been constructed. The system consists of a Penning ion trap contained within an all-metal vacuum system maintained below 3 × 10-19 mbar. Cooling to temperatures of <1 K has been achieved for a large cloud of ions. Single magnesium ions have been trapped and cooled, and quantum jumps have been observed. Quantum jumps in the odd isotope of magnesium (25Mg+) have been simulated. Preliminary results suggest that as well as quantum jumps between the two levels equivalent to the 24Mg+, there are two further types of quantum jump. From experimental observations of 25Mg+ in the trap, the pumping rates between different hyperfine levels due to the laser can be determined and compared with both the predictions of the model and the results for 25Mg+.

    Single frequency, narrow linewidth operation of a 670-nm visible diode laser in an external cavity

    A recently developed method for reducing the linewidth of diode lasers by using weak feedback from a resonant reflector has found wide use because it does not require any modification of the diode laser, but it cannot be used with diode lasers which operate multimode in the absence of feedback. The authors demonstrated that an alternative technique of operating the diode with strong feedback from a frequency selective external cavity does result in single-mode narrow-band output from the gain-guided 670-nm diode lasers. To ensure that the external cavity controls the spectral properties of the laser, it is necessary to put an antireflection coating on the output facet of the diode. Although it may be possible to reduce the linewidth of these diodes using the resonant optical reflector method, the external cavity scheme seems preferable for many applications because of the ease with which the laser can be tuned to a required wavelength.

    Radiative properties of atoms near a conducting plane: An old problem in a new light

    , Physical Review A, Vol: 41, Pages: 1587-1596, ISSN: 1050-2947

    We examine the level shifts and radiation rates of an atom near an infinite, perfectly conducting plane. Following the work of Dalibard, Dupont-Roc, and Cohen-Tannoudji [J. Phys. (Paris) 43, 1617 (1982); 45, 637 (1984)], we distinguish between the effects of radiation reaction and vacuum fluctuation. This separation provides some new physical insight into the nature of cavity modifications of atomic properties. In particular, we are able to identify the Casimir interaction as entirely due to the vacuum fluctuations. © 1990 The American Physical Society.

    Cavity Quantum Electrod Ynamics

    , Advances in Atomic, Molecular and Optical Physics, Vol: 28, Pages: 237-289, ISSN: 1049-250X

    This chapter focuses on cavity quantum electrodynamics. It presents the modifications of the spontaneous radiation rate in a cavity and the shifts of energy levels. The chapter focuses on experimental work, with an outline of a theoretical framework in which the experiments may be understood. In the laboratory, the study of atoms in cavities is a relatively young field in which much of the effort is still aimed at elucidating the basic physical principles at work and demonstrating the elementary modifications of energies and the rates of an atom in a cavity. However, the ability to adjust the electromagnetic spectrum of the vacuum is leading into a remarkable new domain of quantum physics in which atoms can decay from the ground state to an excited state, radiative corrections can be far larger than fine structure, and electromagnetic fields can be prepared with an exact number of photons. This realm of physics is now known as “cavity quantum electrodynamics. © 1991 Academic Press Inc.
