Abstract: Improved Raman Fiber Laser (RFL) generators may include a mid-infrared fiber, e.g., a fiber comprising a tellurite glass, a chalcogenide glass, a fluoride glass, or similar material. A phase-shifted fiber Bragg grating may be inscribed in the fiber. A pump laser generator may be coupled with the fiber in order to supply a pump laser to the fiber. When stimulated by the pump laser, the RFL generator may emit an output laser having a mid-infrared wavelength. A tuner may be used to tune the output laser.

Abstract: An optical resonator made from an elongated fiber having a proximal and distal end. A sphere is created on the distal end by locating the distal end in cylindrically symmetrical heating zone along a centerline. For some embodiments, the distal end is rapidly cooled by allowing it to retract away from the heating zone along the centerline during the formation and solidification of the molten microsphere. The resulting optical resonator has an intrinsic quality factor greater than 106 over the 2.0 to 3.2 μm MIR wavelength range.
