Filamentation of powerful femtosecond beams with a vortex of the topological charge l = 2 in sapphire is studied. A method to control the azimuthal position of filaments by changing the phase difference between two coherent co-axial beams, vortex and vortex-free reference ones, is proposed and demon...
