Near-Diffraction- and Near-Dispersion-Free OAM Pulse Having a Controllable Group Velocity by Coherently Combining Different Bessel Beams Based on Space-Time Correlations
We simulate the generation of a near-diffraction- and dispersion-free OAM pulses with arbitrary group velocities. As the pulse OAM order increases, the group velocity almost remains the same while the temporal pulse width becomes longer.
