Subdiffraction propagation of images using saturated absorption of optical transition. Academic Article uri icon


  • We show how well-developed saturated absorption spectroscopy could be adopted for subdiffraction propagation of optical images. We employ pump beams with appropriate spatial profiles that produce controllable inhomogeneous absorption and dispersion of the medium. We discuss advantages of using super-Gaussian and Laguerre-Gaussian pump beams.
