WebJan 16, 2014 · We review light assisted collisions in a high-density far-off resonant optical trap (FORT). By tuning the parameters of the light that induces the collisions, the effects of the collisions can be controlled. Trap loss can be suppressed even at high atomic densities, allowing us to count the atoms using fluorescence detection. When only two atoms are … WebHere we report a very pronounced and narrow (25 mG) Feshbach resonance in collisions between two triplet ground-state NaLi molecules. This molecular Feshbach resonance has two special characteristics.
WebFIG. 1: Experimental setup. A single atom located by a far-off-resonant trap (FORT) in a confocal arrangement of two aspheric lenses (AL) is made part of a stabilized Mach-Zehnder interferome-ter.

Optical trapping and ions combine unique advantages of independently striving fields of research. Light fields can form versatile potential landscapes, such as optical lattices, for neutral and charged atoms, avoiding detrimental implications of established radiofrequency (rf) traps while ...
WebOct 3, 2008 · We have successfully observed high-resolution spectra of spin-forbidden electric quadrupole transition (1 S 0→3 D 2) in ytterbium (174Yb) atoms. The differential light shifts between the 1 S 0 and the 3 D 2 states in a far-off resonant trap at 532 nm are also measured. For the spectroscopy, we developed simple, narrow-linewidth, and long … WebThe meaning of FAR-OFF is remote in time or space.

WebDec 23, 2024 · We report on the stable effective trapping of cold rubidium atoms by a method for a single optical trap in the near-optical resonant regime. An optical trap with the near-optical resonance condition consists of not only the dipole but also the radiative forces, while a trap using a far-off resonance dominates only the dipole force. We measure the …
WebThe second project that I worked on was constructing an optical trap. The oscillating electric field of a laser in an optic trap induces an oscillating atomic electric dipole moment. A potential is produced that corresponds to the intensity of the laser beam.
