METHOD AND SYSTEM FOR DIFFRACTIVE BEAM COMBINING USING DOE COMBINER WITH PASSIVE PHASE CONTROL
专利汇可以提供METHOD AND SYSTEM FOR DIFFRACTIVE BEAM COMBINING USING DOE COMBINER WITH PASSIVE PHASE CONTROL专利检索，专利查询，专利分析的服务。并且A system and method for combining plural low power light beams into a coherent high power light beam. Optical amplifiers transmit a plurality of light beams propagating at a common wavelength through an array of optical fiber emitters. Each constituent beam is emitted from the array at a different propagation angle, collimated, and incident on a diffractive optical element operating as a beam combiner such that incident beams when properly phased and located are combined into a coherent beam at a desired diffraction order. A beam splitter or a periodic sampling grating on the diffractive optical element directs a low power sample beam to a spatial filter passing resonant mode output back to the optical amplifiers in a ring laser configuration thereby passively synchronizing phases of the constituent beams to maximize combination efficiency of the coherent beam.，下面是METHOD AND SYSTEM FOR DIFFRACTIVE BEAM COMBINING USING DOE COMBINER WITH PASSIVE PHASE CONTROL专利的具体信息内容。
