From: Spatiotemporal optical vortices with controllable radial and azimuthal quantum numbers
a Comparison of spatial projection for intensity profiles of STHG wavepackets for inverse signs of azimuthal quantum number. b Comparison of spatial projection for intensity profiles of STHG wavepackets for inverse signs of spatiotemporal astigmatism. c Scheme for recognizing radial quantum number and azimuthal quantum number of STLG wavepackets.
