摘要：

The development of a fiber laser sensor system which permits efficient interrogation of Bragg grating sensors is reported. A tunable erbium fiber laser which utilizes a broadband mirror and an intracore Bragg grating reflector in a side-pump configuration is described. The wavelength of the laser oscillation is determined by the Bragg grating, which is remotely located and used as a strain sensor. This arrangement is employed in conjunction with a passive wavelength demodulation system (WDS) to form a self-contained fiber laser strain sensor system, allowing efficient interrogation of the Bragg sensor. This device provides interrupt immune sensing of static and dynamic strains with a resolution of 5.4 muepsilon and a bandwidth of 13.0 kHz.
