Jrv. De Aldana et al., Atoms interacting with intense, high-frequency laser pulses: Effect of themagnetic-held component on atomic stabilization - art. no. 013411, PHYS REV A, 6401(1), 2001, pp. 3411
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.
