2017-03-07 · Among these techniques, magneto-optical trapping using a narrow optical transition (linewidth kHz) provides an efficient method to prepare atomic samples of typically 10 8 lanthanide atoms in the 10 μ K temperature range [ 15, 20 ], in analogy with the trapping of Sr and Yb atoms using the intercombination line [ 22, 23 ].
This process is experimental and the keywords may be updated as the learning algorithm improves. Magneto-optical trapping combines the friction force of laser cooling with a “restoring” force depending on the atomic position. In order to realize the position dependent force, a magnetic quadrupole field combined with three orthogonal pairs of counter-propagating laser beams intersect at the center of the magneto-optical trap (MOT), the location where the magnetic field is zero.
