2D Magneto-optical trapping of diatomic molecules.
We demonstrate one- and two-dimensional transverse laser cooling and magneto-optical trapping of the polar molecule yttrium (II) oxide (YO). In a 1D magneto-optical trap (MOT), we characterize the magneto-optical trapping force and decrease the transverse temperature by an order of magnitude, from 25 to 2 mK, limited by interaction time. In a 2D MOT, we enhance the intensity of the YO beam and ...
متن کاملMagneto Optical Trapping of Rb 87
Magneto optical traps brilliantly combine semi-classical optics with modern physics. By carefully controlling the polarization and frequency of laser beams, it is possible to trap and cool atoms down to the millikelvin range at a relatively low cost. This has opened previously inaccessible physical domains to enterprising physicists all around the world, and is responsible for some of the most ...
متن کاملMagneto - Optical Trapping of Chromium Atoms
We have constructed a magneto-optical trap for chromium atoms. Using trapping light at 425 nm and two repumping lasers tuned to intercombination transitions, over 10 atoms were trapped and average densities of over 10 m were obtained. Non-exponential loss of atoms is observed at high densities indicating inelastic collisions between trapped atoms. Over a range of trapping conditions, the densit...
متن کاملMagneto-optical trapping of holmium atoms
We demonstrate sub-Doppler laser cooling and magneto-optical trapping of the rare-earth element holmium. Atoms are loaded from an atomic beam source and captured in six-beam σ+ − σ− molasses using a strong J = 15/2 ↔ J = 17/2 cycling transition at λ = 410.5 nm. Due to the small difference in hyperfine splittings and Landé g factors in the lower and upper levels of the cooling transition the MOT...
متن کاملElectronic Spectral Line Shape of a Diatomic Molecule
The electronic absorption spectral line shape of a diatomic molecule with harmonic potential curves is calculated using the time correlation function formalism. Both the equilibrium shift and the frequency shift of the two linking electronic states ate taken into account. The spectrum is also calculated using the cumulated expansion which is related to the correlation function of the time-d...
