Nettet19. feb. 2024 · Analysis show that the spectral intensity depends on the structure constant of the refractive index, pulse duration, and beam order. On-axis spectral intensity is blue-shifted and off-axis spectral intensity is red-shifted with increasing radial coordinate. From our main results, one derive some published particular cases of the considered beam.

NettetDefinition. When a beam of light is partly blocked by an obstacle, some of the light is scattered around the object, and light and dark bands are often seen at the edge of the shadow – this effect is known as diffraction.

"Nettet26. mar. 2024 · A light beam passing through the moving diffraction grating is, of course, diffracted. Usually multiple beams emerge from the grating, each beam corresponding to a different diffraction order. Each diffracted beam is frequency-shifted by NxF, where F is the frequency of the acoustic wave and N is the diffraction order of the diffracted beam. " - Intensity of diffracted beam
