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.
Recent studies on twisted-light-matter interactions have highlighted the importance of the longitudinal electric field component, which had previously been overlooked. Together with the transverse…
It is well established that the longitudinal component of paraxial optical vortices has a key role in specific atomic quadrupole transitions near the beam axis when the spin and orbital angular…
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…
