Influence of the melting atmosphere on Yb3+/Al3+ co-doped silica glass with powder melting technology
The Yb3+-doped glass is prepared using powder melting technology based on high-frequency plasma. More Yb2+ ions can be formed with decreasing oxidizing conditions. The phenomenon can be reduced or eliminated under pure oxygen during the glass preparation.
