PHOSPHORUS-SILICATE FIBERS SUITABLE FOR EXTENDED BAND AMPLIFICATION
摘要
<p>An optically active phosphorus-silicate glass when pumped to directly excite Er ions provides gain in 1565nm to 1620nm range and comprises in weight percent: SiO2 50 to 92%; Er2O3 0.01 to 2%; P2O5 greater than 5%; and Al2O3 0.0 to 0.3%.</p>
