A vortex beam is a beam with a continuous spiral phase. In other words, the wavefront of the beam is neither planar nor spherical, but rather vortex-like with singularities. The phase of the vortex beam changes around the optical axis in the form of a spiral of 2π integer multiples, and the light intensity at the centre of the beam is zero. Therefore, the vortex beam is also known as dark hollow beam, this optical vortex in the beam propagation process similar to the fluid vortex, there will be around the centre of the phenomenon of rotation.

Optical vortices are mainly used in optical micromanipulation techniques. Compared with traditional methods, optical micromanipulation has the characteristics of no contact, no damage, high reliability, high repeatability and high precision. Photons have their own unique advantages in the micromanipulation of mesoscopic particles. Therefore, the research on the subject of vortex beam is fundamental and forward-looking, it has a profound impact on the understanding of the nature of light, and its potential can be continuously explored.

Based on the vortex beams with different radii at all levels obtained by this experimental system, an optical tweezers experimental platform can be further built, and the optical tweezers platform can be used to capture, manipulate, rotate and trap various sizes and types of micro-nanoparticles, and expand the optical tweezers platform. The control range provides theoretical and technical support for the further development of optical tweezers, optical rotation, optical trapping and nanotechnology. It is a high-level innovative experimental system that takes into account both teaching and research.
