摘要：
Aiming at the problem that the vortex beam is difficult to obtain under laboratory conditions, a vortex beam generation method based on spatial light modulator (SLM) is proposed. The collimated laser beam is modulated into a vortex beam by uploading a spiral phase mask attached to a grating on a SLM. Simulation results verify the effectiveness of the proposed method. The beam obtained from the experimental results also conforms to the properties of the vortex beam.
