Table 2. Comparison of different methods for ultrashort vortex beam generation

Generation method	Advantage	Disadvantage
Spiral phase plate	High damage threshold,low dissipation, greater flexibility	Topological-charge dispersion,group delay
Computer-generatedhologram	Generate anytopological charge	Low conversion efficiency,complicated compensation procedure
Axially symmetric polarizer/axiallysymmetric half-wave plate	High conversation efficiency,applicable to ultrabroadband pulses	Low damage threshold
Uniaxial crystal	Applicable to ultrabroadband pulses,high damage threshold, highconversation efficiency	Only generate single-anddouble-charge vortex
Spiral grating	Compact structure,generate high contrast pulse	Complicate components
Spiral multi-pinhole plate	High damage threshold,easily fabricated	Topological-charge dispersion,low conversion efficiency
Sagnac interferometer	Common-path configuration,applicable to ultrabroadband pulses,high damage threshold	Only generate single-charge vortex
