Radiation-Balanced Silica Fiber Amplifier [PDF]
Physical Review Letters, 2021 We report what we believe to be the first radiation-balanced fiber amplifier - a device that provides optical gain while experiencing no temperature rise. The gain medium is a silica fiber with a 21 um-diameter core highly doped with Yb3+ (2.52 wt.%) and co doped with 2.00 wt.% Al to reduce concentration quenching.
