Difference between vector beams

The difference between vector beams lies in the intensity distribution and polarization state.

1, light intensity distribution difference: the light intensity distribution of ordinary beams is isotropic, that is, the light intensity is the same in any direction. The intensity distribution of vector beam is anisotropic because it can describe the distribution and direction of electric field and magnetic field in space.

2. Polarization state difference: ordinary light beam is unpolarized, that is, electromagnetic waves in light vibrate in random directions. The vector beam can be polarized light, that is, the electromagnetic wave in the light vibrates in a specific direction.
