Abstract :
We consider propagation in air of intense short laser pulse with a phase singularity. Such a pulse can propagate in a self-created plasma channel filamenting and coalescing in a controlled way. Input pulse close enough to the equilibrium state evolves towards vortex soliton. Below breakup power coalesced ring is split into two bright solitons flying off tangentially. Above breaking power a vortex soliton is generated in equilibrium.
