摘要： A technique for correcting wavefront aberrations introduced by large primary optical elements in portions of the electromagnetic spectrum. The aberrations of the primary element are first transferred to a beacon beam and this aberrated beam is interfered with a reference beam in a holographic medium. These beams are then turned off and a beam from a distant object, containing the same aberrations, is allowed to diffract from the hologram. The diffracted beam from the hologram contains the image of the distant object with aberrations removed. Use of this technique permits the construction of large optical elements inexpensively, since surface tolerances of the elements can be substantially relaxed.

摘要： Apparatus, and a corresponding method for its use, for producing a phased array of high-energy laser beams from multiple laser amplifiers. A reference beam produced by a master oscillator senses phase and piston errors in a primary mirror array, and is divided into multiple probe beams, each of which makes multiple passes of its own laser amplifier. The multiple probe beams are together focused into a single phase conjugation cell, which not only produces phase-conjugated reflected beams, to effect compensation for various phase aberrations, but also locks all of the reflected beams together in phase. An arrangement of a birefringent wedge and a quaterwave plate for each of the beams prevents the reflected beams from returning to the master oscillator and facilitates combining of the reflected beams for output as a cophasal array. In a preferred embodiment of the invention, this is accomplished by using the birefringent wedges to deflect each retro-reflected phase-conjugated beam onto the appropriate portion of a monolithic secondary mirror, and then to the primary mirror array.

摘要： A device and corresponding method for optical phase conjugation using a stimulated Brillouin scattering (SBS) medium and resulting in a reduction in the (SBS) threshold level. An incident light beam is brought to a first focus in the SBS medium, and light transmitted through the first focus is brought to a second focus in the SBS medium. Light transmitted through the second focus is brought to a third focus, and so forth through N foci in the medium. The effective SBS threshold level is inversely proportional to the number of foci N, which may be located in separate SBS cells, or may be in a single cell through which multiple passes are made by means of appropriate reflective optics. Laser sources operating in multiple longitudinal modes are handled by spacing the foci at an intergral multiple of the laser resonant cavity length.
