A method and apparatus for projecting a laser beam for communication or guidance purposes wherein transmitted energy goes directly to a receiver area without requiring services of slewing or tracking devices. The energy is precisely directed from a laser transmitter on a missile toward a receiver at a tracking area. By directing the laser energy from a source on the missile during flight and by performing phase conjugating amplification of this laser energy at a tracking area station, atmospheric distortions are removed from the return energy and beam broadening is limited only to the negligible effects of diffraction broadening of the return energy, with the laser return beam being directed almost exclusively back to the missile.
