We investigate the controlled manipulation of the Goos-Hänchen (GH) shift in probe light beams, encompassing both plane and Gaussian beams, when introduced into a cavity housing a highly resonant five-level atomic system exhibiting a combined tripod and Λ (CTL) configuration. This complex scheme arises from the interaction of three atomic ground states with two excited states through five distinct light fields.

We propose a scheme to analyze the generation and detection of optical vortices via spontaneous emission spectra. We consider a five-level M-type atomic system that interacts with two structured coherent light sources and the vacuum radiation field. The photon emitted via spontaneous decay carries information about the orbital angular momentum (OAM) of the newly generated structured light.
