Brief description of the passive coherent combination of two optical beams magnified and / or spectrally widen.

摘要

The present invention relates to a method and a passive device of the coherent combination of two optical beams amplified and / or widened spectrally by at least a bidirectional optical component (a1, a2). According to the invention, the device comprises an interferometer with a division of the amplitude of a ring comprising the optical means of separation and recombination arranged so as to receive an incident optical beam (s) and the spatially separate in a first secondary beam of the input (h) and a second secondary beam of the input (h), the optical guiding means arranged so as to define an optical path in the ring in the interferometer, the at least a bidirectional optical component (a1, a2) being disposed on the optical path of said ring interferometer, said means of separation and recombination being arranged so as to receive and recombining spatially and temporally and a coherent manner, said first secondary beam of the output (h) and said second secondary beam of the output (h), in order to form a coherent beam output.
