It has been shown experimentally for the first time that phase singularities are inherent in not complex amplitude of a monochromatic wave alone, but in arbitrary complex parameter of the field, including its spatial correlation function. Nonlinear-holographic self-conjugation of the wave from of the vortex beams has been implemented also. Product Description popup.authors popup.nrat_date 2020-04-02 Close
