Abstract: A system and method for passing a fiber cable through a fiber connector is presented. A fiber connector includes an outer body and a series of flutes inside the outer body. The outer body forms an interior chamber that has a first opening and a second opening. The first opening allows a coolant to flow into the first opening and the first and second openings allow the fiber cable to pass through the first opening and the second opening and through the fiber connector. A series of flutes are attached to an inner surface of the outer body and extend into the interior chamber. The flutes are spaced apart from each other and extend from the inner surface toward the fiber cable but do not touch the fiber cable when no liquid is flowing in the fiber connector.

Abstract: A fiber optic rotary joint includes a first fiber optic cable operably coupled to one of a stator and a rotor and a second fiber optic cable operably coupled to the other of the stator and the rotor. The stator and the rotor define a free space optical path between the first fiber optic cable and the second fiber optic cable. The rotor is rotatable about an axis of rotation parallel and collinear with an optical axis of at least one end of the fiber optic rotary joint. A first beam conditioning mechanism is configured to condition a light beam emitted from the first fiber optic cable and a second beam conditioning mechanism is configured to focus the conditioned light beam into the second fiber optic cable.

Abstract: A fiber optic cable including a first end and a second end, a core adapted to receive and transmit an optical signal and a cladding layer surrounding the core is disclosed. The fiber optic cable may include a ratio of an outside diameter of the cladding layer to a diameter of the core that decreases from the first end to the second end while the diameter of the core remains substantially uniform. The fiber optic cable may include a first portion of the cladding layer and a second portion of the cladding layer. A uniform outside diameter of the second portion may be less than a uniform outside diameter of the first portion. The fiber optic cable may further include a third portion of the cladding layer. A uniform outside diameter of the third portion may be less than a uniform outside diameter of the second portion.

Abstract: A system and method for increasing the fiber coupling efficiency of diode lasers is disclosed. The diode laser has a diode pump source for generating a force to pump a laser and a double clad fiber directly coupled to the diode pump source instead of coupling to the multimode fiber. The pumped laser is transmitted directly through the double clad fiber thereby increasing the coupling efficiency of the diode pump source. At least one connector is utilized for connecting the double clad fiber and the diode pump source. The connector has at least one adhesive placed in contact with an acrylate coating and not in contact with a glass cladding of the double clad fiber to avoid cladding stripper and fiber splice thereby increasing the fiber coupling efficiency.

Abstract: A system and method for producing Stimulated Raman Scattering (SRS) is disclosed. A single optical fiber or Raman oscillator is optically pumped by a pump laser of sufficient power to generate SRS to generate several Stokes shifts of energy. This generates a multi-wavelength output or a single wavelength with several stokes energy shifts from the pump wavelength. A selective, monolithic-coated Raman fiber oscillator laser is utilized to increase the efficiency of frequency shifting by providing frequency-specific feedback at both facets of a free space coupled optical fiber oscillator. Frequencies that lie several bands away from the primary pump frequency may be efficiently achieved in a fiber oscillator by re-circulating the required stokes-shifted frequencies via selective high-reflection coatings. By re-circulating the intra-band stokes frequencies, the required intensities in each respective frequency will be increased, thereby dropping the respective Raman threshold in the optical fiber.
