    Search for time-reversal-symmetry violation in thallium fluoride using a jet source

    , Physical Review A, Vol: 44, Pages: 2783-2799, ISSN: 1050-2947

    We have looked for a violation of time-reversal symmetry (T) in the molecule thallium fluoride using a rotationally cold beam from a jet source. Our method was to search for a frequency shift of the thallium nuclear magnetic resonance when an external electric field of 29.5 kV/cm was reversed with respect to a magnetic quantization axis. The measured shift, (1.42.4)×10-4 Hz, was interpreted as a null result and constitutes a tenfold improvement in sensitivity over the previous measurement. Accordingly, our measurement has reduced the upper limits on the proton and electron electric dipole moments and on other T-violating weak couplings that can be deduced from the frequency shift. © 1991 The American Physical Society.

    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.

    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.

    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.
