Abstract
A system and method generates confined electromagnetic radiation emanating from a remote position along a line of sight. The system includes a laser arrangement and a wavefront modifier. The laser arrangement generates at least one laser beam. The wavefront modifier produces a spatial arrangement of foci of the laser beam directed along the line of sight. The foci of the laser beam induce plasma filaments within an atmosphere at the remote position along the line of sight. The plasma filaments emit the electromagnetic radiation emanating from the remote position along the line of sight.
