Single-frame measurement of ultrafast spatiotemporal vortex pulses
We demonstrated a simple method to quantitatively characterize the spatiotemporal orbital angular momentum (ST-OAM) of light. Our method can measure the presence of ST-OAM, space-time topological charges, OAM helicity, pulse dispersion, and beam divergence.
