Abstract

Spectral characteristics of rubidium atoms confined in a dark magneto-optical trap (DMOT) are measured, including probe absorption spectra and atom density as a function of the cooling and repumping laser frequencies. The trap can capture and cool more than 2.5 × 10 8 rubidium atoms, confining them in a hyperfine state weakly perturbed by the laser beams used to form the trap. The optical density of the trapped atomic cloud approaches 9. A qualitative model of the DMOT operation is presented, based on the experimental results obtained.

Probe spectroscopy of cold rubidium atoms in MOT

Vasily M. Entin, I. I. Ryabtsev

The experimental results of the probe spectroscopy of laser cooled Rb atoms in a magneto-optical trap (MOT) are presented. The absorption spectra of the probe transition were expected to be significantly different, and indications of coherent population trapping were expected for the dark repumping transition.

Pulsed filling of a dark magnetooptical trap for rubidium atoms

P. L. Chapovsky

The parameters of a dark magnetooptical trap for rubidium atoms are measured. The rubidium atoms captured and cooled in the trap occupy a hyperfine level of the ground electronic state, which does not interact with cooling laser radiation. The pulsed filling of the trap is produced due to desorption of rubidium caused by irradiation by a short (1 ms) light pulse. The trap captures and cools 2.5 × 10 8 rubidium atoms approximately for 0.2 s. The absorption spectra of a weak probe field by cold atoms are obtained, which demonstrate a good spectral resolution of the hyperfine structure in the excited state. This structure is completely hidden by the Doppler broadening in rubidium vapours at room temperature.

Rubidium lifetime in a dark magneto-optical trap

O. I. Permyakova, A. V. Yakovlev, P. L. Chapovsky

Measurements of rubidium lifetime in a dark magneto-optical trap (DMOT) was performed at various populations of the bright and dark hyperfine states of the trapped atoms. The rubidium lifetime in the trap appeared to be shorter if the atom spent more time in the bright state. A simple explanation of this effect is based on the increase of the cross-section of rubidium collisions with the surrounding warm atoms upon rubidium electronic excitation.

Experimental studies on a dark magneto-optical trap for 85Rb

This work is concerned with density enhancements in a laser-cooled sample of 85Rb using a dark magneto-optical trap (MOT). The density of atoms in a standard MOT is limited to approximately ~1011 atoms/cm3 due to radiation pressure and collisions. The dark MOT (DMOT) circumvents problems associated with radiation pressure in the atom cloud. To create a DMOT, a donut-shaped repump beam is projected on to the cloud of 85Rb. The dark region in the center of the donut is attenuated by ~10^(-4) compared to the bright outer ring. Atoms which encounter this dark region in the repump beam are scattered to the lower hyperfine ground level, F = 2, otherwise known as the dark hyperfine level. Additionally, a depump beam is used to force more atoms into F = 2. Results using free-space spectroscopy are presented to demonstrate the effect of the donut-shaped repump beam and the depump beam on the population distribution of the atoms in the hyperfine ground states. A tapered optical fiber is used to measure the quality of the DMOT via a parameter, p, and a strong population transfer from the bright, F = 3, to the dark, F = 2, hyperfine ground level is demonstrated. The tapered fiber, with a waist of ~ 1 micron, is made from commercially-available optical fiber and is used to detect fluorescence from the cold 85Rb coupled into the fiber guided modes. This work lays the foundation for optical nanofiber absorption spectroscopy with a small number of atoms in an optically-dense system.

Compact magneto-optical trap for rubidium atoms

P. L. Chapovsky

The characteristics of a magneto-optical trap (MOT) using small-diameter cooling laser beams are considered. Trapping and cooling of Rb atoms from the surrounding gas of warm atoms takes place in the trap. A compact (140 μm) and stable atomic cloud is obtained with a density of 7 × 10 10 cm −3 , which is three orders of magnitude higher than the density of the surrounding gas.

Measurement of the lifetime of rubidium atoms in a dark magneto-optical trap

O. I. Permyakova, A. V. Yakovlev, P. L. Chapovsky

The lifetimes of rubidium atoms in a dark magneto-optical trap are measured at different populations of the 'bright' and 'dark' hyperfine states of captured atoms. It is found that the lifetime of atoms in the trap decreases if they spend more time in the bright state. A simple explanation of this effect is proposed which is based on the increase in the transport cross section for collisions of thermal rubidium atoms surrounding the trap with cold rubidium atoms upon their electronic excitation.
