Complete energy conversion between light beams carrying orbital angular momentum using coherent population trapping for a coherently driven double- Λ atom-light-coupling scheme

Year: 2019

Type: article

Abstract: A scheme to transfer the orbital angular momentum between two light beams with efficiency up to unity is theoretically demonstrated. The method uses a double-$\mathrm{\ensuremath{\Lambda}}$ atomic system, a pair of spatially dependent control beams, and the two targeted probe beams that carry optical vorticity.
