Abstract: A fiber laser system comprises a main body, wherein the main body includes one or more fiber laser system components and a first wall hingedly attached to the main body along a first edge, the first wall having a first wall open position and a first wall closed position and a plurality of feed fiber management and splicing components mounted to the first wall. Additionally and/or alternatively, the laser system may comprise a cooling plate hingedly attached to the main body, the cooling plate has a cooling plate open position and a cooling plate closed position. Additionally and/or alternatively, the laser system may include a fiber management tray hingedly mounted to the cooling plate, the fiber management tray having a fiber management tray open position and a fiber management tray closed position.

Abstract: Optical fiber structures for generating a single mode, saddle shaped output beam include first and second lengths of fiber. The first length of fiber has a first input end configured to receive a single mode gaussian beam. The second length of fiber has a second input end coupled to an output end of the first length of fiber. The second length of fiber includes a centrally located anti-guiding core and an annular guiding region coaxially encompassing the centrally located anti-guiding core.

Abstract: Multi-clad optical fiber cladding light stripper (CLS) comprising an inner cladding with one or more recessed surface regions to remove light propagating within the inner cladding. A CLS may comprise such recessed surface regions along two or more azimuthal angles about the fiber axis, for example to improve stripping efficiency. One or more dimensions, or spatial distribution, of the recessed surface regions may be randomized, for example to improve stripping uniformity across a multiplicity of modes propagating within a cladding. Adjacent recessed surface regions may abut, for example, end-to-end, as segments of a recess that occupies a majority, or even an entirety, of the length of a fiber surrounded by a heat sink. One or more dimensions, or angular position, of individual ones of the abutted recessed surface regions may vary, according to a regular or irregular pattern.
