Abstract:   (187 Views)

In this paper, a scheme to achieve the coherent population transfer in a four-level double-Λ atomic system utilizing the coherent beams with Laguerre-Gaussian profile is proposed. It is demonstrated that a maximal population transfer is achieved for a special value of the relative phase of the applied fields. The results is then compared with a similar configuration, but for the laser pulses with the usual Gaussian profiles and is concluded that using the Laguerre-Gaussian modes can result in more population transfer. The suggested scheme may hold great practicality for the realization of the
population transfer in the quantum systems with multiple states.
