  • MID-INFRARED OPTICAL FIBERS WITH ENHANCED OH-DIFFUSION RESISTANCE
    Publication number: 20240069284
    Abstract: Mid-infrared-transparent optical fiber products with enhanced resistance to OH diffusion are disclosed, which may be used fiber laser oscillator and amplifiers systems. In one embodiment, an optical fiber product may include optical fiber configured for propagation of mid-infrared radiation toward a light-radiating endface of or coupled to the optical fiber, and a diffusion barrier disposed on the light-radiating endface and configured for allowing the mid-infrared radiation emanating from the light-radiating endface to pass therethrough and for preventing OH diffusion therethrough toward the light-radiating endface.
    Type: Application
    Filed: November 6, 2023
    Publication date: February 29, 2024
    Applicant: Université Laval
