Vector and scalar vortex beams that exist on the higher-order Poincaré sphere have many applications, such as microscopy, imaging, laser machining, and communication in free space and in fibres.

Wang Anting from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a method for multidimensional manipulation of polarization and phase based ...

Concept. In contrast to the complexity and challenges of producing OAM beams and vector vortex beams from lasers, the control of polarization or SAM inside laser cavities is a well-established ...

Using the laser as a replacement for the CRT’s electron beam, [Seb] was able to code a reasonably playable vector-graphic version of Asteroids on a large projections screen. Even the audio is ...
