Embodiment Construction
[0031] The present invention will be further described below in conjunction with drawings and embodiments.
[0032] The invention relates to a system and method for generating a non-diffraction Bessel light field with different spatial polarization state distributions by using a polarization converter and a metal disk. The generated Bessel light field has vector properties, non-diffraction transmission, and spontaneous Restoration properties can be widely used in optical communication, particle manipulation, biophotonics and nonlinear optics and other fields.
[0033] see figure 1 , one A system for generating a non-diffraction vector Bessel light field, comprising: a light source 1 for generating linearly polarized laser light; a beam expander collimator 2 for beam expanding and collimating the linearly polarized laser light emitted from the light source 1; Converter 3 is used to convert the expanded linearly polarized laser light into a vector light field with non-uniform...
