Vortex beams carry orbital angular momentum (OAM), and have wide application prospects in optical manipulation, optical communication, and quantum optics. To produce ultrashort vortex pulses, we combine vortex beams with the time domain control technique. The method is very important in physical experiments performed under extreme strong field conditions and the researches about ultrafast nonlinear spectroscopy and precision laser material processing. In this paper, the research progress on ultrashort vortex pulse generation methods at home and abroad in recent years is summarized. The main methods for generating ultrashort vortex pulses are reviewed, and the advantages and disadvantages of each method are compared and analyzed.
