  • Abstract
    It is found that Ca additive effectively suppresses the photo-darkening effect in Yb-doped silica fibre even at 6.0 wt% of high Yb2O3 concentration. Ca ion works as a stabiliser to maintain the Yb3+ valence state. It is hypothesised that this phenomenon may reflect the local charge balance effect in silica glass. This Yb-Ca co-doped silica fibre can be useful for high-power fibre lasers.
