Abstract: Optical vortices are structures of the electromagnetic field with a spiral phase ramp about a point-phase singularity, carrying orbital angular momentum (OAM). Recently, OAM has been imprinted to short-wavelength radiation through high-order harmonic generation (HHG),… read more here.

Abstract: The possibility of restructuring the spectral density of a random light beam up to three times along the propagation path in free space is demonstrated. This can be achieved by prescribing special correlations and different… read more here.
