Paper Abstract

The sensitivity is an important issue for intra-cavity absorption gas sensors (ICAGS). In this paper, the ICAGS based on erbium-doped fiber ring lasers (EDFRL) are modeled using propagation equations, from which the expressions of the signal-to-noise ratio (SNR) and the sensitivity of the system are deduced. The influence of the pump power and the total attenuation of the system on the performance of the ICAGS are simulated theoretically and measured experimentally. The absorption signal of acetylene is detected by adjusting the state of the system. And concentration calibration of acetylene is realized finally.
