In recent years, partially coherent beams have attracted much attention due to their unique optical properties and rich physical connotations.Partially coherent beams have unique advantages in many fields of application. Different applications have different requirements for their beam characteristics. Therefore, Coherent beams are controlled.This paper introduces the research progress of the phase modulation of partially coherent beams and its application in basic research, and emphatically expounds the theoretical model of the coherent beams carrying the vortex phase and the twisted phase, the experimental production, the optical properties and the related application basis. Beam transmission characteristics play an important role in modulation, beam shaping, particle capture, atmospheric laser communications, optical imaging and nonlinear optics and other fields has important application prospects.
