Two-photon bound-bound atomic transitions induced by LG beams
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 selected two-photon transitions starting from the ground state of the atomic system. We numerically evaluate these two-photon transition matrix elements for selected transitions in Ca+ employing the truncated summation method. We provide a comparison with corresponding transitions induced by a Gaussian beam and present an estimation of the relative strength when the two different types of light beams are employed.
We investigate the interaction of atoms with a Laguerre-Gaussian beam near the vortex center where an annular nodal area exists on and around the…
We present the theoretical framework and the approximations needed to numerically simulate the response of alkali metal atoms under multi-photon excitation.
