| 摘 要： | 对一种高效的宽带（80nm）双程分立式拉曼放大器的特性进行了理论及实验研究。该拉曼放大器中利用一端镀有金膜的光纤作为宽带反射镜，信号光及泵浦光均被反射而第二次经历增益光纤。与传统的前向泵浦的拉曼放大器相比，该拉曼放大器的增益提高了约150％。此外，分析了影响增益的几种因素，包括泵浦间的相互拉曼作用以及光纤的长度。

| Abstract: | The behaviour of a high efficient double-pass discrete Raman amplifier with 80nm bandwidth was studied theoretically and experimentally. In this Raman amplifier, by using a one-end gilt fibre as the broadband reflector,signals and multi-pump are simultaneously reflected to propagate through the gain fibre for a second time in the opposite direction of the input. An increase in net gain of more than 150% has been achieved compared with that in the typical co-pumped Raman amplifier. The advantages of this new configuration have been studied by comparing with the currently existing Raman amplifier configurations. Also, the influencing factors for the gain increase have been analysed, including the pump-to-pump Raman interactions and the length of gain fibre. |
