H+2 in superintense laser fields: Alignment and spectral restructuring
Abstract
In superintense, relatively high-frequency fields, H+2 presents a strikingly different behavior from that found at lower frequencies. By applying the high-frequency Floquet theory of laser-atom interactions, we predict for the ground state progressive alignment of the molecular axis with the direction of a linearly polarized field as the intensity increases, and persistence of the bond strength. The energy spectrum undergoes complete restructuring: while the field-free rotational levels become librational, they are gradually promoted with respect to the vibrational ones.
