Generating Bessel-Gaussian Beams with Controlled Axial Intensity Distribution

Generating Bessel-Gaussian Beams with Controlled Axial Intensity Distribution

This paper investigated the diffraction of a Gaussian laser beam on a binary mask and a refractive axicon. The principles of the formation of a zero-order Bessel beam with sharp drops of the axial field intensity edges were discussed. A laser optical system based on an axicon for the formation of a...
