摘要： An optical fiber positioner having an elongated base with sidewalls and a longitudinally extending throughbore. A flexible optical fiber extends through the throughbore and has one end protruding outwardly from an end surface of the base. A plurality of actuators are secured to the sidewalls of the base so that an end of each actuator is positioned adjacent the end of the base. A crossbeam is then connected to the ends of each actuator so that the crossbeam moves laterally relative to the base in unison with the deflection of the actuators. The crossbeam has an opening through which the optical fiber extends so that the optical fiber deflects in unison with the lateral movement of the crossbeam. Various fixtures for assembly of the optical fiber positioner are also shown.

摘要： A method and apparatus for coherent beam combining in an array of laser beam collimators. The array of laser beam collimators includes an array of a plurality collimating lenses, each lens intercepting a respective one of a plurality of divergent laser beams. Each collimating lens is joined with adjacent collimating lenses such that an output aperture is formed with a common vertex of the adjacently joined collimating lenses. A concave mirror is positioned a distance from the common vertex for receiving a fraction of each of the collimated laser beams that passed through a portion of each of the collimating lenses that are adjacent to the common vertex, and then providing reflected fractional collimated laser beams. A sensor intercepts the reflected fractional collimated laser beams so as to provide a signal that is applied to synchronize the phase of each of the collimated laser beams.

摘要： A technique for delivery of a divergent laser beam emitted with a free-space laser fiber facet, the beam having an optical power, into an optical waveguide. An optical axis of the laser beam is aligned approximately along a propagation Z direction into the optical waveguide. The fiber facet is located in a first plane perpendicular to the Z direction. The waveguide includes an input, direction, and X-Y position of the input in a second plane. The waveguide includes fluctuations in a X-Y-Z position of the input and fluctuations in direction. The laser beam is transformed into a collimated beam by re-directing a propagation of the laser beam, shifting the laser beam parallel to the Z direction, and focusing the laser beam into the input. The speed of transformation of the laser beam is greater than an instant speed of the fluctuations. A maximum optical power is delivered into the waveguide.

摘要： A method for mounting an optical fiber within a tube in which the optical fiber is positioned through the tube so that a portion of the fiber protrudes outwardly from the distal end of the tube. A curable material, such as an adhesive, is then applied to the optical fiber portion which, upon curing, forms a flexible solid material having the refractive index less than refractive index of cladding material of said fiber optic. The outwardly protruding portion of the fiber is then retracted back into the tube so that the flexible solid material isolates the fiber portion from the tube. In addition, different clamping assemblies are provided for attaching protective sheathing for the optic fiber to a mount for the optic fiber which permit easy disassembly and removal.

摘要： A method and apparatus for controlled displacement, rotation and deformation of parts of a fiber optic collimator so as to provide multiple degrees of adjustment freedom that are decoupled one from another, for adjusting the path of a light beam, comprising: an output elongate hollow node for passing a light beam therethrough and towards a lens, and an elongate hollow base node having separate top and bottom parts connected to each other by opposed ends of a plurality of flexible rods that restrict the relative movement between the top and bottom parts of the base node to substantially only translational parallel movement. Opposed portions of the top and bottom parts of the base node each include a respective screw and an opposed slanted surface, which upon interaction, develop a shearing force which is applied to the top and bottom parts of the base node and cause a translational parallel relative movement therebetween.
