Effect of composite vortex beam on a two-dimensional gain assisted atomic grating
We propose an atomic grating based on an electromagnetically induced transparency phenomenon that switches between zeroth-order diffraction to a distinct higher-order diffraction pattern by driving a planar gaseous medium of a four-level tripod ( $\pitchfork$ ) atoms with three laser beams: modulati...
