We studied the field structure and 3-D propagation on diffraction of a multi circular segment-shaped laser beam. Diffraction of a laser beam with the shape of the multi circular segments (two, four and six) was investigated. We have observed for the

The light field structure on diffraction of a circular segment-shaped laser beam was studied. At distances of 6–20 cm from a segment-shaped aperture obstructing a circular laser beam, the formation of the beam structure propagating in a slow-expans
