The article presents the results of the formation of a polychromatic edge dislocation. A complex Bragg hologram formed as a complex of two gratings with similar characteristics is used as a device employed for this purpose. It is shown that, under resonant illumination of such a grating in the direction of the zero order, two waves are formed with practically equal intensities, forming a low-frequency interference pattern, at the minima of which edge dislocations are observed. The main idea of the method for the formation of a polychromatic edge dislocation is that such a grating is illuminated by a converging radiation beam with a sufficiently wide spectrum. In this case, the structure itself chooses the resonance angles of illumination of the hologram, and identically localized partial spectral gratings are formed in the zero order. The data of experimental studies are presented. The discussion considered the prospects for the formation of polychromatic azimuthally and radially polarized beams
The transverse energy fluxes (both instantaneous and averaged) arising under the superposition of two quasi-plane waves are considered in this paper. The case of superposition when the frequencies of the interacting beams are different is analyzed. The cases of superposition of coaxial orthogonally (linearly and circularly) polarized waves are considered. The mechanisms of forming the distribution of characteristics of the resulting averaged transverse component of the Poynting vector are established. The data of computer simulation are presented.
