Résumé : | Introducing a spatial chirp into a pulse with a longitudinal vortex, such as a standard pulsed Laguerre–Gauss beam, results in a vortex pulse with an arbitrary orientation of the phase line singularity between longitudinal and transverse, depending on the amount of chirp. Analytical expressions are given for such pulses with arbitrary topological charge valid at any propagation distance. |
