摘　　要：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.In order to obtain high-concentration doped erbium ions in silica-based fiber, we manufactured Er^3＋ -Bi^3＋ -Ga^3＋ co-doped fiber using MCVD and solution doping technique. The concentration of Er3＋ in thefiber was about 5.24×10^25/m^3. We described a new method to measure the degree of clustering in the Er^3＋ -Bi^3＋ -Ga^3＋ co-doped fiber using fiber transmission experiment. Compared with other methods, the new method is simpler and more accurate. By the new method, the degree of clustering in Er^3＋ -Bi^3＋ -Ga^3＋ co-doped fiber was determined. It was shown that co-doped Bi^3＋ -Ca^3＋ strongly increased the Er^3＋ solubility in the silica-based fiber.
