Title: Efficient loading of a He* magneto-optic trap using a liquid He cooled source

Abstract

We report loading large numbers (up to 3x10{sup 9}) of metastable triplet helium atoms into a magneto-optical trap using an atomic beam derived from a liquid He (LHe) cooled dc discharge source. Moreover, we compare the effect of liquid N{sub 2} cooling to LHe cooling the source and demonstrate that LHe cooling offers a significant increase in performance.

  • We report a study on the loading of a Rb dark magneto-optical trap from a current-controlled getter source. The effect of changing the temperature and number density of the background atoms on the cold atomic population in the dark state has been investigated by passing current of different magnitudes through the getter source. We observe that the dark state collection rate of the cold atoms is maximized for an optimum value of the getter current used. In our experiments, cold atoms in the dark state have been collected with the maximum collection rate 3.6 x 10{sup 7} atoms/s and backgroundmore » atom collision rate {gamma} = 1.9 {+-} 0.2 s{sup -1} for the getter current {approx}4 A.« less
  • We have obtained fast loading of a rubidium magneto-optical trap and very high collection efficiency by capturing the atoms desorbed by a light flash from a polydimethylsiloxane film deposited on the internal surface of a cell. The atoms are trapped with an effective loading time of about 65 ms at a loading rate greater than 2x10{sup 8} atoms per second. This rate is larger than the values reported in literature and is obtained by preserving a long lifetime of the trapped atoms. This lifetime exceeds the filling time by nearly two orders of magnitude. Trap loading by light-induced desorption frommore » siloxane compounds can be very effectively applied to store and trap a large number of atoms in the case of very weak atomic flux or extremely low vapor density. It can be also effectively used for fast production of ultracold atoms.« less
  • We report on a directional atomic beam created using an alkali metal dispenser and a nozzle. By applying a high current (15 A) pulse to the dispenser at room temperature we can rapidly heat it to a temperature at which it starts dispensing, avoiding the need for preheating. The atomic beam produced is capable of loading 90% of a magneto-optical trap (MOT) in less than 7 s while maintaining a low vacuum pressure of <10{sup -11} Torr. The transverse velocity components of the atomic beam are measured to be within typical capture velocities of a rubidium MOT. Finally, we showmore » that the atomic beam can be turned off within 1.8 s.« less
  • We report the observation of direct, two-color photoassociative ionization (PAI) in collisions between {sup 85}Rb atoms optically cooled and confined in a magneto-optical trap. We also measure the resulting R{sub 2}{sup +} ion spectrum and compare it to earlier trap-loss fluoresecence spectra. Unlike PAI in Na, which ionizes principally by collisional autoionization, the Rb{sub 2}{sup *} intermediate photoionizes directly to Rb{sub 2}{sup +} in a fixed optical field. These observations confirm PAI as a sensitive and broadly applicable spectroscopic tool.
  • Three-dimensional quantum scattering calculations predict that the degree of optical shielding of cold collisions saturates with increasing intensity very differently from two-state models and is sensitive to the polarization of the shielding light. We report measurements showing how suppression of Na photoassociative ionization (PAI) rates is sensitive to the intensity and polarization of the shielding laser. At higher intensities, circular polarization suppresses PAI rates an order of magnitude more effectively than linear polarization, in qualitative agreement with our model calculations. {copyright} {ital 1996 The American Physical Society.}
