WebN2 - The behavior of atoms in an optical far-off resonance trap is found to depend strongly on the trap polarization. Large loss rates occur unless the polarization is perfectly linear or perfectly circular, in which case exponential lifetimes up to 10 s are observed. Through optimization of trap loading, samples of 4×106 atoms are obtained in ... WebJan 1, 2008 · The photoionization rates are obtained by measuring the lifetimes of Rydberg atoms produced inside of a 1064-nm far off-resonance trap and comparing the lifetimes to corresponding control experiments in a magneto-optical trap. Experimental results for the control experiments agree with recent theoretical predictions for Rydberg state lifetimes ...

Transfer to the far-off-resonance lattice is accom-plished by a simultaneous linear turn-off and turn-on of the near- and far-off-resonance potentials over a’200-ms pe-riod. During the MOT-3D molasses and near-resonance lat-tice phases a separate laser provides repumping from the 6S1/2(F53) hyperfine ground state; this … WebOur trap is produced by a Nd:YAG laser which can operate in either a contnuous-wave (cw) or mode-locked, pulsed mode. In particular, we have studied how the transfer of ultra … assistant rh militaire

WebIII. BLUE-DETUNED DIPOLE TRAP AND MICROWAVE SYSTEM As discussed in the previous section, the atoms should be trapped with the minimum disturbance to their coherence properties. Our dipole trap aims to decrease the photon scat-tering and differential ac Stark shift introduced by the trap-ping laser. We use a far off-resonance … WebNov 4, 2008 · We have examined loading of 85Rb atoms into a shallow Far-Off-Resonance Trap (FORT) from an optical molasses and compared it to loading from a Magneto-Optical Trap (MOT). We found that substantially more atoms could be loaded into the FORT via an optical molasses as compared to loading from the MOT alone.
