Coherence properties of nanofiber-trapped cesium atoms.
We experimentally study the ground state coherence properties of cesium atoms in a nanofiber-based two-color dipole trap, localized ∼ 200 nm away from the fiber surface. Using microwave radiation to coherently drive the clock transition, we record Ramsey fringes as well as spin echo signals and infer a reversible dephasing time of T(2)(*) = 0.6 ms and an irreversible dephasing time of T(2)(') =...
متن کاملObservation of cold collisions between trapped ions and trapped atoms.
We study cold collisions between trapped ions and trapped atoms in the semiclassical (Langevin) regime. Using Yb+ ions confined in a Paul trap and Yb atoms in a magneto-optical trap, we investigate charge-exchange collisions of several isotopes over three decades of collision energies down to 3 mueV (k_{B}x35 mK). The minimum measured rate coefficient of 6x10;{-10} cm;{3} s;{-1} is in good agre...
متن کاملThermalization of fast cesium 5D3/2 atoms in collisions with ground-state cesium atoms
We have investigated collisions involving fast, excited Cs atoms produced by photodissociating Cs2 molecules with a pulsed dye laser. The velocities of the atoms in the 5D state formed by the process Cs2sX Sg d+"vpump→Cs2→Css5Dd+Css6Sd are much greater than typical thermal velocities associated with the cell temperature. Using a narrow-band cw probe laser to observe the increased Doppler broade...
متن کاملImproving Raman velocimetry of laser-cooled cesium atoms by spin-polarization
We study the peformances of Raman velocimetry applied to laser-cooled, spinpolarized, cesium atoms. Atoms are optically pumped into the F = 4, m4 = 0 ground-state Zeeman sublevel, which is insensitive to magnetic perturbations. High resolution Raman stimulated spectroscopy is shown to produce Fourier-limited lines, allowing, in realistic experimental conditions, atomic velocity selection to one...
متن کاملPopulation change in the fine structure levels of cesium atoms using chirped laser
Here, the population transfer between two specific levels of Cesium atomunder the influence of chirped laser source has been numerically investigated. The maingoal of this study is the engineering of the population transfer between the 62S1/2 and 62P1/2levels of Cesium which is corresponding to its D1 transition line using a chirped lasersource. Constructing the system Hamiltonian, as well as t...
