  • Abstract
    The enhancement of photodarkening resistivity as high as 95% is achieved through H2-treatment of Yb-doped fiber, irrespective of Yb-concentration. H2-blocking employing the pump excitation in the fiber indicates negligible photodarkening even after post-diffusion of interstitial-H2.
