Abstract: Vectorial vortex beams (VVBs) are new type of structured optical fields with helical phase and spatial inhomogeneous polarization. It has already shown broad applications in domains like optical tweezers, rotator detection, optical communication, high-resolution imaging, quantum information and other fields. With the continuous deepening of research, the requirements for more complex optical fields of VVBs are getting higher and higher, which brings huge challenges to the generation technology of VVBs. In addition, how to represent such complex optical fields of VVBs more practically and completely is also an important basis for its application. The author’s team has been engaged in the research on the manipulation and application of structured beams like VVBs, and has proposed a variety of extra- and intra-cavity generation of VVBs with selective output modes. In this paper, recent advances of VVB representation and intra-cavity generation are introduced and reviewed, including the four-parameter representation, the intra-cavity regulation of transverse and longitudinal modes of VVBs, and the eye-safe solid VVB laser as well.
