4 Light-Dressed Spectroscopy of Molecules

Fig. 4.7 Light-dressed absorption (upper panel) and stimulated emission (lower panel) spectra of
Na 2 obtained at 0.5 K with 662 nm wavelength dressing fields having different intensities
At finite temperatures an additional complication arises. Namely, one needs to
take into account the field-free rotational states of a closed-shell diatomic molecule
which are characterized not only by J but also by the m quantum number, which
stands for the projection of the rotational angular momentum onto the chosen space-
