Abstract

We present a study on characteristics of a magneto-optical trap (MOT) as an optical lattice. Fluorescence spectra of atoms trapped in a MOT with a passively phase-stabilized beam configuration have been measured by means of the photon-counting heterodyne spectroscopy. We observe a narrow Rayleigh peak and well-resolved Raman sidebands in the fluorescence spectra which clearly show that the MOT itself behaves as a three-dimensional optical lattice. Optical-lattice-like properties of the phase-stabilized MOT such as vibrational frequencies and lineshapes of Rayleigh peak and Raman sidebands are investigated systematically for various trap conditions.

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. Investigations of optical processes for laser cooled and trapped atoms are described. Fluorescence from Cs atoms in a magneto-optical trap is detected under conditions of very low atomic density. Discrete steps are observed in the fluorescent signal versus time and are associated with the arrival and departure of individual trapped atoms. Histograms of the frequency of occurrence of a given level of fluorescence exhibit a series of uniformly spaced peaks that are attributed to the presence of N = 0, 1, 2 atoms in the trap. In addition, numerical absorption and emission spectra for three-level [...], [...], and V systems under intense radiations are calculated. Absorption spectra for a [...] system is used to explain the probe-wave amplification and absorption spectra recorded for Cs atoms cooled and confined in a magneto-optical trap, in which novel spectral features of narrow frequency widths with single-pass gain exceeding 20% are observed. The consequence of the optical gain is demonstrated to lead to negative radiation pressure, which is investigated together with other mechanical forces in the trap. Various alternative trapping schemes in three-level and two-level atoms are proposed as possible means to compress an atomic sample and demonstrated for a two-level magneto-optical trap.

Bound and free atoms diagnosed by the recoil-induced resonances: One-dimensional optical lattice in a working magneto-optical trap

We report on studies of simultaneous trapping of $^{85}\mathrm{Rb}$ atoms in a magneto-optical trap (MOT) and one-dimensional optical lattice. Using Raman pump-probe spectroscopy, we observe the coexistence of two atomic fractions: the first consists of free, unbound atoms trapped in a MOT and the second is localized in the micropotentials of the optical lattice. We show that recoil-induced resonances allow not only temperature determination of the atomic cloud but, together with vibrational resonances, can also be used for real-time, nondestructive studies of the lattice loading and of the dynamics of systems comprising unbound and bound atomic fractions.

Magneto-optical trap as an optical lattice

Harald Schadwinkel, U. Reiter, V. Gomer +1 more

We study the magneto-optical trap (MOT) as an optical lattice with a setup providing full phase control for all light fields. Although completely different light fields are possible for various phases, we have found experimental evidence that stored atoms are generally localized in micropotentials of the six-beam lattice. The influence of the phase variation is surprisingly small, suggesting that the robust behavior of the MOT is a consequence of this fact. We find furthermore good agreement of our experimental data with a simple theoretical model which reduces the complicated MOT to a description of steady-state atoms localized at points of the deepest adiabatic light-shift potential.

Experimental observation of microwave induced resonances in magneto-optic trap

Vasily M. Entin, I. I. Ryabtsev, Yu. V. Brzhazovskiǐ

Results on study of MOT fluorescence in presence of microwave field applied to ground state splitting of atoms in trap are presented. Experiments are performed with rubidium atoms in conventional three circular polarized retroreflected beams magneto-optical trap setup in the next conditions. To make trapping, two external cavity diode lasers frequency locked to saturated absorption peaks at D-2 line of rubidium are used. The power of each laser is about 6 mW. The locking circuit allowed the tuning of offset frequency within wing of saturation absorption peak via computer.
