Abstract
We derive ultracold atom-atom photoassociation line shapes valid for intense light fields and investigate laser power effects in sodium and rubidium photoassociation to the purely long range 0g- symmetry state. We consider intensities up to few hundreds W/cm2, a strongly saturating intensity for typical transitions of experimental interest. For these intensities the 0g- rotational spectrum is still well resolved; however, it is essential to couple the photoassociation resonance to both s- and d-wave ground state channels. A low energy d-wave shape resonance can have a profound effect on the line shape. Understanding the line shape is essential for precision spectroscopic analysis and could improve the extraction of ground-state scattering properties such as scattering lengths.Citation
