Self-similar spatiotemporal solitary waves Bessel-Hermite optical lattices

An exact self-similar solution to a （3＋l）-dimensional nonlinear Schrodinger equation with gain in the BesselHermite lattice is obtained analytically. The stability of the analytical solution is confirmed by using numerical simulation. It is shown that the light bullet has a stable ellipsoid or vorte...

Beschreibung
Zusammenfassung:	An exact self-similar solution to a （3＋l）-dimensional nonlinear Schrodinger equation with gain in the BesselHermite lattice is obtained analytically. The stability of the analytical solution is confirmed by using numerical simulation. It is shown that the light bullet has a stable ellipsoid or vortex profile and a linear spatiotemporal chirp.
