Abstract: The invention provides a method and a system for generating a polarized propagation-invariant light field. The system includes a laser source, a spatial light modulator, a computer, a first lens, a shading element, a first quarter-wave plate, a second quarter-wave plate, a second lens, and a beam combining element. In the present invention, two Laguerre-Gaussian mode beams that satisfy a particular Gouy order relationship are generated, and orthogonal even polarization is applied to the two Laguerre-Gaussian mode beams.

The light field generated in the present invention simultaneously has linear polarization, elliptical polarization, and circular polarization in a cross section of the light field, and in a propagation process of the light field in free space, apart from normal spot size scaling, polarization distribution remains unchanged.
