Frequency Conversion of Optical Vortex Arrays Through Four-Wave Mixing in Hot Atomic Gases
Arrays of multiple vortices were transferred from infrared to the blue region of the optical spectrum. This demonstration was achieved by inducing four-wave mixing in an atomic gas with a Gaussian beam and a quasi-invariant propagation beam of the Mathieu type. The latter structure was analyzed in t...
