Abstract:
The new optical system for conversion of linear polarized laser beams (as the most typical for laser radiation) into cylindrical vector beams (radial or azimuthal, as more effective in various applications), and also into various nonuniform polarized beams is developed and experimentally tested. The scheme is based on coherent superposition mode beams with use of phase diffractive grating allowing to change mode’s phase shift without application of additional elements. Simplicity and universality of the scheme is reached owing to application of diffractive optical elements for generation prescribed mode distributions of necessary orientation in space, and also for forming simultaneously several different transverse modes in different rays for their further combination.

Key words:
nonuniform polarized beams, radial and azimutal polarization, extracavity polarization converter, coherent superposition, diffractive optical elements.
