  • Apparatus and method for enabling quantum-defect-limited conversion efficiency in cladding-pumped Raman fiber lasers
    Patent number: 9450373
    Abstract: Cladding-pumped Raman fiber lasers and amplifiers provide high-efficiency conversion efficiency at high brightness enhancement. Differential loss is applied to both single-pass configurations appropriate for pulsed amplification and laser oscillator configurations applied to high average power cw source generation.
    Type: Grant
    Filed: March 5, 2010
    Date of Patent: September 20, 2016

  • Optical waveguides having flattened high order modes
    Patent number: 8798422
    Abstract: A deterministic methodology is provided for designing optical fibers that support field-flattened, ring-like higher order modes. The effective and group indices of its modes can be tuned by adjusting the widths of the guide's field-flattened layers or the average index of certain groups of layers. The approach outlined here provides a path to designing fibers that simultaneously have large mode areas and large separations between the propagation constants of its modes.

  • Annealing mold and retainer for making a fiber optic current sensor
    Patent number: 5935292
    Abstract: An annealing mold and fiber retaining device includes a fiber holding plate having fiber channels and an annealing insert. Retainers are provided for attachment to the plate to retain fibers in the channels. After annealing, the annealing insert is replaced by a packaging insert. The fiber holding plate is mounted between a support plate and a cover plate. The mounted plates include a coextensive current conductor port and the plates are mounted in a housing which includes vibration mounts for isolating the plates from vibration within the housing.
