WebIn our experiment, a single cesium atom prepared in a large-magnetic-gradient magneto-optical trap (MOT) can be efficiently transferred into a 1064-nm far-off-resonance microscopic optical dipole trap (FORT). The efficient transfer of the single atom between the two traps is used to determine the trapping lifetime and the effective temperature of the … WebMay 18, 1997 · Published 18 May 1997. Physics. Physical Review A. We calculate the heating rates arising from laser intensity noise and beam pointing fluctuations in far off resonance optical traps. Achievement of long heating time constants imposes stringent requirements on the laser noise spectra. View via Publisher. physics.ncsu.edu.
WebOct 14, 2000 · The size of alkali vapour Bose-Einstein condensates is determined by the number of atoms which can be collected in a magneto-optical trap. This number is limited by processes involving near-resonant light. A possible technique to exceed the number limit is to load a conservative trap which is spatially separated from the laser cooling region. … Webdipole trap aims to decrease the photon scattering, damaging to the coherence, and differential ac Stark shift introduced by the trapping laser.
