We present the theoretical framework and the approximations needed to numerically simulate the response of alkali metal atoms under multi-photon excitation.

We report theoretical results for the transition amplitudes of two-photon transitions induced in a one-active-electron atomic system by a LG10 beam. We identify the excitation pathways for…

We investigate the quantized states of a two-level Rb atom that is trapped by the optical dipole potential when the atom interacts with a helical optical tube light field.
