Abstract

Discriminative measurement of temperature and strain sensing is proposed and experimentally demonstrated based on erbium-doped fiber laser (EDFL) and Brillouin erbium fiber laser (BEFL). The EDFL and the BEFL share the same laser cavity. The EDFL can be easily switched to BEFL when the Brillouin pump is injected into the cavity. Longitudinal modes beat frequency generated from EDFL and Brillouin frequency shift originated from BEFL are monitored to discriminate strain and temperature. The simultaneous measurement errors of strain and temperature are within ± 25.8µe and ± 0.8°C.
