| Description | Journal: Laser Physics A four-wavelength Fabry–Pérot Brillouin–erbium fiber laser (FP-BEFL) with sensing element of 10 m single mode fiber (SMF) and gain media of 6 m erbium-doped fiber (EDF) for temperature measurement is proposed and demonstrated. Stabilization of FP-BEFL is effectively improved by the modified FP structure with a Faraday rotation mirror (FRM). Then, temperature sensitivity of every wavelength is obtained by measuring the beat frequency shift between four-wavelength and reference light. 1.036 MHz/°C, 2.006 MHz/°C and 3.104 MHz/°C temperature elevation coefficient of the different wavelength respectively keep in good agreement with theoretical value. About ±0.3 dB power fluctuation of different wavelength is achieved by optical spectrum analyzer (OSA) in 1 h. This new configuration has promising applications in temperature sensing with high stabilization, high sensitivity and cost effectiveness. |
