چکیده

We have investigated a new radiation pressure trap which relies on optical pumping and does not require any magnetic field. It employs six circularly polarized divergent beams and works on the red of a Jg −→ Je = Jg + 1 atomic transition with Jg ≥ 1/2. We have demonstrated this trap with cesium atoms from a vapour cell using the 852 nm Jg = 4 −→ Je = 5 resonance transition. The trap contained up to 3 · 10 atoms in a cloud of 1/√e radius of 330 μm. Europhys. Lett., 27, (8), pp. 569-574, 10 September 1994. Unité de recherche de l’Ecole Normale Supérieure et de l’Université Pierre et Marie Curie, associée au CNRS (UA18).

Trapping and Manipulation of Laser-Cooled Metastable Argon Atoms at a Surface

This thesis discusses experiments on the all-optical trapping and manipulation of lasercooled metastable argon atoms at a surface. A magneto-optical surface trap (MOST) has been realized and studied. This novel hybrid trap combines a magneto-optical trap at a metallic surface with an optical evanescent-wave atom mirror. It allows laser-cooling and trapping of atoms in contact with an evanescent...

Optical pumping model of the polarization for the TRINAT experiment

The TRIUMF Neutral Atom Trap (TRINAT) has an active experimental program to measure angular correlations in the decay of spin-polarized K. An overview of our recent progress including a successful run in December 2012 is described in our other report. This report will focus on our progress in developing a better model of the optical-pumping process that polarizes the trapped atoms. Optical pump...

Atom chip apparatus for experiments with ultracold rubidium and potassium gases.

We present a dual chamber atom chip apparatus for generating ultracold (87)Rb and (39)K atomic gases. The apparatus produces quasi-pure Bose-Einstein condensates of 10(4) (87)Rb atoms in an atom chip trap that features a dimple and good optical access. We have also demonstrated production of ultracold (39)K and subsequent loading into the chip trap. We describe the details of the dual chamber v...

Efficient loading and cooling in a dynamic optical evanescent- wave microtrap

– We calculate the loading efficiency and cooling rates in a bichromatic optical microtrap, where the optical potentials are generated by evanescent waves of cavity fields at a dielectric–vacuum interface. The cavity modified nonconservative dynamic light forces lead to efficient loading of the atoms as well as cooling without the need for spontaneous emission. Steady–state temperatures well be...
