Degenerate Raman sideband cooling of 40K atoms

  title={Degenerate Raman sideband cooling of 40K atoms},
  author={Elad Zohar and Yanay Florshaim and Oded Zilberman and Amir Stern and Yoav Sagi},
We report on the implementation of degenerate Raman sideband cooling of 40 K atoms. The scheme incorporates a 3D optical lattice, which confines the atoms and drives the Raman transitions. The optical cooling cycle is closed by two optical pumping beams. The wavelength of the laser beams forming the lattice is close to the D 2 atomic transition, while the optical pumping is operated near the D 1 transition. With this cooling method, we achieve temperature of ∼ 1 µ K of a cloud with ∼ 10 7 atoms…

Degenerate Raman sideband cooling of K39

We report on the first realization of sub-Doppler laser cooling of 39K atoms using degenerate 3D Raman sideband cooling. We take advantage of the well-resolved excited hyperfine states on the D1

Efficient Laser Cooling of 85Rb Atoms to the Recoil Temperature Limit

We demonstrate laser cooling of 85Rb atoms in a two-dimensional optical lattice. We follow the two-step degenerate Raman sideband cooling scheme, Kerman el al., Phys. Rev. Lett. 84, 439 (2000), where

Direct Laser Cooling to Bose-Einstein Condensation in a Dipole Trap.

This work presents a method for producing three-dimensional Bose-Einstein condensates using only laser cooling and finds that during the final cooling stage at atomic densities above 10^{14}  cm^{-3], careful tuning of trap depth and optical-pumping rate is necessary to evade heating and loss mechanisms.

Resolved-Sideband Raman Cooling to the Ground State of an Optical Lattice

We trap neutral Cs atoms in a two-dimensional optical lattice and cool them close to the zero point of motion by resolved-sideband Raman cooling. Sideband cooling occurs via transitions between the

3D raman sideband cooling of cesium atoms at high density

We laser cool 5x10(7) Cs atoms to a spin-polarized phase space density of 1/30, the highest ever obtained by laser cooling. It is achieved by compression and polarization gradient cooling in a 3D

Sideband Cooling Of Neutral Atoms In A Far-Detuned Optical Lattice

Sideband laser cooling using stimulated Raman transitions is performed on trapped cesium atoms. The confinement is produced by a far–off-resonance dipole trap consisting of two crossed YAG beams

Beyond optical molasses: 3D raman sideband cooling of atomic cesium to high phase-space density

A simple, general purpose method to cool neutral atoms based on 3D degenerate Raman sideband cooling in optical lattices and remains efficient even at densities where the mean lattice site occupation is close to unity.

Creation of a Bose-condensed gas of 87Rb by laser cooling

Direct laser cooling of a gas of rubidium-87 (87Rb) atoms to quantum degeneracy is demonstrated, which is fast and induces little atom loss.

Sub-Doppler laser cooling of fermionic 40K atoms in three-dimensional gray optical molasses

We demonstrate sub-Doppler cooling of 40K on the D1 atomic transition. Using a gray-molasses scheme, we efficiently cool a compressed cloud of 6.5 × 108 atoms from ∼4 mK to 20 μK in 8 ms. After
