Abstract: In an example, a tandem pumped fiber amplifier may include a seed laser, a first section coupled to an output of the seed laser, and a second section coupled to an output of the first section. The first section may operate as an oscillator, and may receive pump light from one or more diode pumps, and may the first section may be arranged to convert the one or more diode pumps into a tandem pump. The second section may operate as a power amplifier, and may include a length of a single or plural active core fiber. The tandem pumped fiber amplifier may be arranged to mitigate spectral broadening related to four-wave mixing.

Abstract: In an example, a tandem pumped fiber amplifier may include a seed laser, one or more diode pumps, and a single or plural active core fiber. The single or plural active core fiber may include a first section to operate as an oscillator and a second different section to operate as a power amplifier. The one or more diode pumps may be optically coupled to the first section of the single or plural active core fiber, and the seed laser may be optically coupled to the single active core or an innermost core of the plural active core fiber.

Abstract: An apparatus for scattering light may include: an optical fiber having a first length; and a sleeve, having a second length shorter than the first length, around the optical fiber. The optical fiber may include: a core; and cladding around the core. The sleeve may include fiber-optic material. The fiber-optic material may be substantially polymer-free. An outer surface of the sleeve may be roughened to scatter the light out of the sleeve through the roughened surface. A method of forming an apparatus for scattering light may include: providing a sleeve having a first length, the sleeve having inner and outer surfaces; providing an optical fiber having a second length longer than the first length; passing the sleeve around the optical fiber or threading the optical fiber through the sleeve; and roughening at least a portion of the outer surface of the sleeve.

Abstract: Some embodiments may include a packaged laser diode assembly, comprising: a length of optical fiber having a core and a polymer buffer in direct contact with the core, the length of optical fiber having a first section and a second section, the first section of the length of optical fiber including a tip of an input end of the optical fiber, wherein the polymer buffer covers only the second section of the first and second sections; one or more laser diodes to generate laser light; means for directing a beam derived from the laser light into the input end of the length of optical fiber; a light stripper attached to the core in the first section of the length of optical fiber. Other embodiments may be disclosed and/or claimed.
