Steering photoassociation of cold 85Rb atoms by two-color slowly-turned-on and rapidly-turned-off laser pulses

Journal of Physics B: Atomic, Molecular and Optical Physics, 2023
Photoassociation (PA) of 85Rb atoms from the ground X1Σg+ state to the excited A1Σg+ and b3Πu states by two-color laser pulses at 100 μK×kB is investigated by using quantum wavepacket method.

Investigation of photoassociation with full-dimensional thermal-random-phase wavefunctions.

Journal of Chemical Physics, 2021
By taking the femtosecond two-photon photoassociation (PA) of magnesium atoms as an example, we propose a method to calculate the thermally averaged population, which is transferred from the ground X1Σg + state to the target (1)1Πg state, based on the ...

Observation of photoassociation spectroscopy of ultralong 37D5/2 + 6S1/2Cs2 Rydberg molecules.

Journal of Chemical Physics, 2020
We present an experimental observation of 37D5/2 + 6S1/2Cs2 Rydberg-ground molecules by employing a two-photon photoassociation method. Two distinct Rydberg-ground molecular signals, deep and shallow bound molecules, are observed at the red detuning of ...

The effects of Feshbach resonance on spectral shifts in photoassociation of Cs atoms.

Physical Chemistry, Chemical Physics - PCCP, 2020
We study the effects of magnetic Feshbach resonance on the shifts in photoassociation (PA) spectra of ultracold Cs atoms. A series of atom loss spectra show a linear variation of the frequency shift with the PA laser intensity at different magnetic ...

Photoassociation of Cold Ca Atoms

Physical Review Letters, 2000
We present the first measurement of a photoassociative spectrum of an alkaline earth element near the dissociation limit. The observed spectrum of Ca2 formed from cold atoms shows the regular vibrational series with the characteristic spacing of the 1/R3 asymptotic potential.

Photoassociation of Ultracold Sodium Atoms

Physica Scripta, 2003
Using ultra-cold atoms a new technique of photoassociation spectroscopy has been developed. The technique has an unprecedented resolution and can be used to obtain high-resolution data on singly and doubly excited states of diatomic molecules. We describe the principle of the technique and show results for one specific case, namely the Na2 molecule.
