Atoms interacting with intense, high-frequency laser pulses: Effect of themagnetic-held component on atomic stabilization - art. no. 013411

At sufficiently high laser intensities, the magnetic-field component of the laser field can strongly influence the stabilization of atoms in the high- frequency regime by inducing motion along the laser pulse propagation direc tion. Using a two-dimensional model atom, we investigate how the duration o f the laser pulse affects stabilization in this nondipole regime. Results o btained using a fully spatially dependent vector potential are compared to a long-wavelength approximation. We also discuss nondipole effects when the atom interacts with two counterpropagating pulses.
