摘要：A device for steering a wavefront of electromagnetic radiation comprising apumping means for coherently pumping a plurality of phase conjugate mirrors with amonochromatic coherent beam having a wavelength substantially the same as thewavelength of the wavefront. The device further comprises an array of phase conjugatemirrors wherein the acceptance of each phase conjugate mirror, for conjugate reflectionof the wavefront, is pointing in substantially the same direction, and the phase conjugatemirrors are composed of material responsive to the beam wavelength. The device furthercomprises a Fourier transform lens, a control reflector positioned such that the reflectedbeam from the reflector back to the lens is within the acceptance angle of the ray, and abeam splitter positioned between the array and the control reflector for extracting asteered beam. Each phase conjugate mirror may provide amplification of the wavefront,or amplifying lasers may be used. The phase conjugate mirrors may be positioned closeto each other, or telescopes may be used in conjunction with each phase conjugate mirrorto expand each beam.
