摘要：

The performance of an erbium-doped fiber (EDF) ring laser based intra-cavity gas sensor is investigated theoretically and experimentally. A theoretical model for analyzing the effects of the EDF parameters and the system parameters on the performance of this gas sensor was established using coupled rate equations and propagation equations. We investigated a number of specific cases and suggested practical choices of their parameters. Experiments with two cavity losses were conducted to test the system sensitivity enhancement and the trend of the results matched well with the theoretical prediction. The results showed sensitivity enhancement factors ranged from 17-20 in the experimental system can be achieved.
