  • Broadband short pulse fiber lasers capable of generating output spectra broader than gain bandwidth
    Patent number: 9031100
    Abstract: Implementations and examples of fiber lasers based on fiber laser cavity designs that produce self-similar pulses (“similaritons”) to achieve a pulse spectral bandwidth greater than a gain spectral bandwidth based on a spectral broadening fiber segment and a spectral filter to ensure the proper similariton conditions.
    Type: Grant
    Filed: February 11, 2013
    Date of Patent: May 12, 2015
    Assignee: Cornell University
    Inventors: Frank W. Wise, Andy Chong, William Renninger

  • Mode-locked fiber laser based on narrowband optical spectral filtering and amplifier similaritons
    Patent number: 8787411
    Abstract: Implementations and examples of mode-locked fiber lasers based on fiber laser cavity designs that produce self-similar pulses (“similaritons”) with parabolic pulse profiles with respect to time at the output of the fiber gain media to effectuate the desired mode locking operation. An intra-cavity narrowband optical spectral filter is included in such fiber lasers to ensure the proper similariton conditions.
