Vector quality measure for vector beams [PDF]
SPIE Proceedings, 2016 Vector beams are spatial modes of light with spatially variant polarization states in the transverse profile. Over the years, vector beams have found their way into plenty of applications ranging from material processing and lithography to electron acceleration and particle trapping.

An interference scheme for generating inhomogeneously polarized laser radiation using a spatial light modulator [PDF]
Компьютерная оптика, 2020 An optical system for converting linearly polarized laser beams into cylindrical vector beams is developed and experimentally investigated. The scheme is based on the coherent addition of mode beams using a Mach-Zehnder interferometer. The simplicity and

Influence of initial phase of polarization on tight focusing of vector beam
Results in Optics, 2021 Generally, the influence of initial phase of polarization distribution of incident vector beams always is ignored in its tight focusing, because it just induce the whole rotation of polarization distribution.

Parabolic-accelerating vector waves
Nanophotonics, 2021 Complex vector light fields have become a topic of late due to their exotic features, such as their non-homogeneous transverse polarisation distributions and the non-separable coupling between their spatial and polarisation degrees of freedom (DoF).
