In this article, we simulate the formation of diffraction-free beams, which combine some of the properties required for technologies such as planar microscopy, information coding and optical manipulation. Analytical functions in combination with a diaphragmed annular spatial spectrum are proposed as an optical beam. The analysis is carried out at distribution in the free environment and lens systems.

Effective formation of diffraction-free laser beams based on the diaphragm of the annular spatial spectrum
