摘　　要：提出了一种新的光纤气体传感网络的有源复用系统 ,将锁模激光技术与光纤环形内腔激光气体传感技术相结合 ,提出并实现一套以锁模光纤环形腔激光器为复用基础的光纤内腔激光气体传感网络系统 。A new way of multiplexing fibre optic sensors for gas detection based on intra-cavity spectroscopy with fibre lasers is investigated. An active mode-locked fibre laser is used to address the sensing network and provide preliminary experimental results to demonstrate the principle of operation. It is a new technique for combining intracavity spectroscopy with a sensor network and has the potential for multiplexing a few tens of gas sensors with low cost and high sensitivity.
