From: Ultrafast bursts of tailored spatiotemporal vortex pulses
Burst of spatiotemporal vortex pulses with defined time-varying quantum numbers on both radial and azimuthal indices. a Measured iso-intensity profile of this spatiotemporal vortex bursts, exhibiting a train of time-varying STLG wavepackets with variable p and ℓ. The temporal separation is 4 ps. The isovalue is set to 5% of peak intensity. b Retrieved phase distribution in the meridional plane, showing time-varying spatiotemporal phase singularities and edge dislocations. c Modal weight analysis of each comb teeth at specific times within the burst, the power distributing at the desired radial (\(p\)) and azimuthal (\({\mathcal{l}}\)) index is 82.5%, 51.34%, and 84.4%, respectively
