Figure 2 | Synthesized spatiotemporal vortex burst with time-varying T-OAM values. a, Measured iso-intensity profile of the spatiotemporal vortex burst in the space-time domain, which has a ~20 ps temporal length and a 2.8 ps temporal pitch. The red and blue color denotes the negative and positive topological charge respectively. b, Transverse OAM modal power and purity analysis of the synthesized spatiotemporal vortex bursts, exhibiting time-varying transverse OAMs with high mode purity.
