    摘要： A method and apparatus is described that use an index-of-refraction profile having a significant central dip in refractive index (or another tailored index profile) within the core of a gain fiber or a gain waveguide on a substrate. The benefits of this central dip (more power with a given mode structure) are apparent when an input beam is akin to that of a Gaussian mode. In some embodiments, the invention provides a fiber or a substrate waveguide having an index profile with a central dip, but wherein the device has no doping. Some embodiments use a central dip surrounded by a higher-index ring in the index of refraction of the core of the fiber, while other embodiments use a trench between an intermediate-index central core portion and the ring, or use a plurality of rings and/or trenches. Some embodiments use an absorber in at least one core ring.

    摘要： An optically pumped laser has a gain medium positioned inside of an optical resonator cavity and disposed about a resonator optical axis. An optical pumping source is positioned outside of the optical resonator cavity. A reflective coupler with a coupler body, and an interior volume passing therethrough is positioned proximal to the optical pumping source. Light from the pumping source passes into an entrance aperture of the reflective coupler to an exit aperture of the reflective coupler positioned distal to the optical pumping source. The interior volume of the reflective coupler is bounded by a reflective surface, an entrance aperture and the exit aperture, and is substantially transparent to radiation from the optical pumping source. The reflective surface has a high reflectivity matched to radiation from the optical pumping source. The reflective coupler directs radiation from the optical pumping source into the optical resonator cavity and gain medium, conditioning the numerical aperture and spatial intensity distribution across the exit aperture.

    摘要： An optical amplifier includes at least one amplification stage having a saturation recovery time of less than one (1) millisecond. The amplification stage includes a gain medium operable to receive at least one pump signal and to receive from a multiple span communication link an optical signal comprising a leading edge. The at least one pump signal and the optical signal travel in the same direction at approximately the same speed through at least a portion of the gain medium. In one particular embodiment the leading edge of the optical signal after passing through a plurality of amplifiers when received by a receiver coupled to the communication link comprises a peak power that is no more than ten times the average power of the optical signal at the receiver.

    摘要： An amplifier uses a two-dimensional array of cw diodes to produce a pump beam. A coupler is positioned to receive the pump beam. The coupler reduces a cross-sectional dimension of the pump beam and creates a modified pump beam. A vanadate gain medium is positioned adjacent to the coupler. The vanadate gain medium absorbs at least a portion of the modified pump beam and is positioned to receive an input beam from an input beam source and produce an amplified output beam.

    摘要： Apparatus and method for distributed absorption of pump light over a length of delivery fiber that is, for example in some embodiments, fusion spliced to an end of a multiply clad gain fiber that has significant unused pump light at the end of the gain fiber. In some embodiments, this includes coupling a fiber amplifier to a passive-core delivery fiber that includes a distributed pump dump. In some embodiments, at an output end of the amplifying fiber there is still a significant amount of pump power. If all this pump power is dumped in one small place (e.g., at a splice between the amplifying fiber and a passive delivery fiber) a hot spot will result, leading to unreliable devices that fail (have catastrophic changes in operating performance). The present invention provides a distributed pump dump built into a delivery fiber that is passive to the signal in its core.

    摘要： A third-harmonic crystal has a Brewster-cut dispersive output surface for separating the p-polarized fundamental and third-harmonic beams without introducing losses into the beams. The output surface of the third-harmonic crystal is optically uncoated, and thus insensitive to potential ultraviolet (UV)-induced damage. Frequency doubling and tripling lithium triborate (LBO) crystals are used with a Brewster-cut Nd-YAG active medium in a resonant cavity to generate UV light at 355 nm from infrared (IR) light at 1064 nm. Except for the tripling crystal output surface, the doubling and tripling crystal optical surfaces are normal-cut and anti-reflection (AR) coated.
