使用MCVD法结合溶液掺杂技术制作了铒铋镓共掺的石英基光纤.根据光纤吸收谱,得出其中铒离子浓度是5.24×1025/m3.然后提出了一种新的利用透射率测定掺铒光纤的团簇率的实验方法,该方法相比于以前的方法更简单有效.利用该方法,测得了自制铒铋镓共掺光纤中团簇率.通过与前人的结果相比较,充分说明铋和镓的掺入大大提高了铒离子在石英基光纤中的溶解度,抑制了铒离子形成团簇. According to the optical absorption spectrum, the erbium ion concentration was 5.24 × 1025 / m3, and then a new method using transmittance measurement of doped Erbium fiber cluster ratio experiment method, the method compared to the previous method is more simple and effective.Using this method, we measured the self-made erbium gallium arsenide cluster fiber co-doped fiber ratio by comparing with the previous results, sufficient The incorporation of bismuth and gallium greatly enhanced the solubility of erbium ions in silica-based fibers, inhibiting the formation of clusters of erbium ions.
