Abstract: A method for assembling a beam combiner array including providing an array block having a back wall, a front surface and a plurality of aligned channels extending from the back wall to the front surface, where a bore extends through the back wall and into each channel, and providing a lens array including a plurality of lenses. The method further includes securing the lens array to the front surface of the block so that one of the lenses is aligned with each channel and threading a separate hollow core fiber through one of the bores in the back wall so that an end of the fiber is positioned within the channel. The method also includes aligning each fiber to the lens array so that a beam that propagates down the fiber is emitted into the channel, focused by the lens and emitted from the array as a collimated beam.

Abstract: A beam combiner array assembly including an array block having a back wall and a front surface and a plurality of aligned and sealed channels extending from the back wall to the front surface. A lens array including a plurality of lenses is secured to the front surface of the block so that one of the lenses is aligned with each channel, and a plurality of fiber flanges are secured to the back wall of the block so that a separate one of the flanges is aligned with each channel. A hollow core fiber extends through each flange and the back wall so that an end of the fiber is positioned within one of the channels. A beam that propagates down each fiber is emitted into the channel, focused by the lens and emitted from the assembly as a collimated beam.

Abstract: A system for fabricating an optical element. The system includes means for welding an array of fibers to the optical element, means for measuring an angle error and a position error of each fiber, means for calculating a correction for each fiber for the angle error and the position error and means for correcting the angle and position of each fiber using the calculated corrections.

Abstract: An internally switched fiber laser amplifier is disclosed and claimed. The switch is integrated directly into the fiber amplifier, so that the output power from each fiber amplifier can be switched between N selectable output fibers with minimal (approx. 1%) loss. The switch may be a close coupled pump switch, a spherical mirror or a planar mirror. The fiber laser amplifier may switch both pump and source lights, or may switch only the pump light then combine it with the source light before sending it to a gain amplifier.

Abstract: A method for fabricating a beam shaper array assembly, where the beam shaper array assembly changes the shape of a plurality of beams. The method includes providing an optical endcap having a plurality of connector stems, welding a fiber to each of the stems to form an emitter array and positioning a beam shaper array adjacent to the endcap opposite to the stems. The method also includes measuring an angle error and a position error of each fiber, calculating a correction for each fiber for the angle error and the position error and correcting the angle and position of each fiber using the calculated corrections.
