| 摘 要： | 基于小信号开关增益原理,采用抽运光-探测波法,利用SLD(超辐射激光二极管)作为宽带小信号探测光源,快速测量出了标准单模光纤(G.652)的频移为0.5～20 THz内的喇曼增益系数,测量结果和文献中已有的值基本吻合,所测得的光纤喇曼增益系数可用于光纤喇曼放大器的理论和实验研究,该方法同样可以对其他类型光纤的喇曼增益系数进行测量.

| Abstract: | Basing on the on-off gain of fiber Raman amplifier under small signal ,the Raman gain coefficient for frequency shift between 0.5 and 20 THz in standard single mode optical fiber(G.652) is measured by pump-probe method through a super luminescent diode (SLD) as a broadband small signal probe The result agrees with that provided by the reference and can be used in the research on RFA. The method is fit for the measurement of Raman gain coefficient in other optical fibers as well. |
