矢量涡旋光束的模式连续可调生成技术

Vectorial vortex beams are a new kind of structure beams, with anisotropic polarization distributions and carrying orbital angular momentum. Such unique features contribute to their applications in lots of domains as optical communications, optical tweezers, laser material processing, etc. Different applications need different polarization and phase distributions. So generating vectorial vortex beams with continuously adjustable polarization and phase distributions is of great importance. In this paper, we introduce some approaches for generating vectorial vortex beams developed in our group, including generation of single vectorial vortex beams outside the cavity and generation of vectorial vortex beams arrays.
