Competition of magneto-optical and optical lattice trapping

Abstract

Measurements are reported that probe the redistribution of cold /sup 85/Rb atoms between a continuously working magneto-optical trap (MOT) and 1D optical lattice imposed over it. The performed procedure provides a simple and versatile way of a real-time, nondestructive monitoring of the cold atom transfer from the non-localized MOT phase into the optical lattice.

Cold atoms diagnostics by non-linear spectroscopy

Summary form only given. We have performed a series of measurements of absorption and wave mixing with cold Rb atoms contained in a magneto-optical trap (MOT). Contrary to several previous experiments our measurements were taken without switching off the trapping /spl sigma//sup +/-/spl sigma//sup -/ beams, and thus allow for a direct probing of MOT conditions.

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

Maria Brzozowska, Tomasz Brzozowski, Jerzy Zachorowski +1 more

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.

High Resolution Spectroscopy of Cold, Trapped Atoms

Pump-probe spectroscopy of cold, trapped atoms is discussed with particular attention to mechanisms specific for cold atoms and potential diagnostics applications.The discussion is illustrated with experimental results obtained with 85 Rb atoms trapped in a magneto-optical trap.Most important applications are non-destructive, real-time velocimetry (thermometry) and analysis of optical lattice dynamics.

Measurement of the collisional trap loss rate in magneto-optically trapped {sup 7}Li and {sup 6}Li

Nicholas W. M. Ritchie, Yangyang Xiao, E. Abraham +1 more

Collisions between ultra-cold (T << 1K) atoms confined in a magneto- optical trap (MOT) may result in the ejection of atoms from the trap. These collisional loss processes, which involve ground state/excited state collisions, fundamentally limit the density attainable in MOT traps. Although accurate calculations of collision rates between ultra-cold atoms require precise knowledge of the molecular potentials over a long range, the loss rate for Li was recently predicted to be significantly less than for the other alkali metals. Motivated by this result, we are measuring the collisional loss rate of Li in a vapor-cell MOT using a red-detuned laser beam to catalyze the collisions, similar to recent experiments using Rb and Cs. We will report our progress to measure the trap loss rate for {sup 6}Li and {sup 7}Li, which will be compared to investigate an isotopic dependence, as was recently observed for Rb.

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.

Note: Investigation of atom transfer using a red-detuned push beam in a double magneto-optical trap setup

Surjya Prakash Ram, Satya Ram Mishra, S. K. Tiwari +1 more

We present our results on transfer of cold (87)Rb atoms from a vapor cell magneto-optical trap to ultrahigh vacuum magneto-optical trap (UHV-MOT) using a red-detuned continuous wave push beam in a double-magneto-optical trap setup. We find that use of retro-reflected red-detuned push laser beam results in higher number in UHV-MOT than the number obtained without retro-reflection of push beam.
