  • Mid-infrared broadband laser using cascaded nonlinearities in mid-infrared fiber and nonlinear crystal
    Patent number: 11815782
    Abstract: A mid-infrared broadband laser including: a femtosecond laser configured to generate a near-infrared light; nonlinear waveguide configured to broaden and/or shift a spectrum of the light from the femtosecond laser; and a nonlinear medium configured to generate a broadband light by mixing spectral components of the output from the non-linear waveguide. Optionally, at least one dispersion compensation element may be placed between the femtosecond laser and the nonlinear waveguide and/or between the nonlinear waveguide and the nonlinear medium.
    Type: Grant
    Filed: February 15, 2022
    Date of Patent: November 14, 2023
    Assignee: Thorlabs, Inc.
