Abstract

High-concentration Er:YAG single-crystal fibers have been grown using the laser-heated pedestal growth technique. Instability in the melt and concomitant opacity of fibers were observed at source concentrations higher than 15 mol.%. Spectroscopic examination shows that broadening of the linewidth of the ⁴I(13/2) → ⁴I(15/2) transition is strongly dependent on Er³⁺ concentration.

摘要

采用激光加热基座生长技术生长出高浓度掺铒 YAG 单晶光纤。在源浓度高于 15mol%时，观察到熔体不稳定性和光纤同时不透明。光谱研究表明， ⁴I(13/2) → ⁴I(15/2)跃迁线宽的展宽强烈依赖于 Er³⁺浓度。
