摘要： A method and apparatus for compensating for phase fluctuations incurred by an optical beam travelling through free space, especially a turbulent atmosphere. A transmitting station transmits a plurality of uniquely tagged optical beams through free space. The plurality of uniquely tagged optical beams are received at a receiving station, where a parameter of each uniquely tagged optical beam is quantified. Information associated with the quantified parameter for each uniquely tagged optical beam is then sent back to the transmitting station via a wireless feedback link. Using the information, the transmitting station adjusts at least one uniquely tagged optical beam to compensate for phase fluctuations.

摘要： A laser apparatus having multiple laser devices coupled together. The laser devices comprise optical fibers with laser active regions. Each of the fibers has a reflector disposed at one end and is connected to a combiner on the other end. A laser pump device for each fiber provides pump energy to the laser active regions. Light propagating in the fibers interacts so as to form inphase states. The array of fibers may be coupled either in pairs or altogether between the reflector and the laser active region.

摘要： A multiple-fiber, stretched, fused and cleaved coupler designed to act as an output window to a fiber laser array or fiber-coupled laser array, in which the stretch, length and/or position of the fibers is chosen facilitate the in-phase oscillation of the lasers in the array. The in-phase oscillation of the lasers is facilitated by making one or more of the fibers interferometrically dark. The other fibers, the interferometrically lit ones, are made to have fairly uniform intensity under the same collimated illumination.

摘要： A coherent laser receiver for receiving encoded light which may have propagated over an aberrated path, situated between a source of the encoded light and the coherent receiver. The coherent laser receiver comprises a bundle of optical fibers arranged in an array to receive light, as encoded from a distant optical transmitter or reflective surface, the encoded light from the distant optical transmitter or reflective surface is received by at least a majority of the fibers in the array. A plurality of light amplifiers is provided for amplifying the received encoded light. A control apparatus coherently combines a composite output of the bundle of optical fibers, the control apparatus includes at least one detector for detecting the a portion of the received encoded light, an output of the at least one detector being utilized to control the plurality of light amplifiers so that differential phases among individual fibers associated with said at least one detector in the bundle are minimized by said light amplifiers. A coherent detector is responsive to the composite output of the bundle for providing an output signal representative of the encoded information from the source.
