Paper Abstract

We propose a sensing scheme of an erbium-doped fiber (EDF) ring laser for multi-monitoring of radiation dose and strain simultaneously. The EDF and fiber Bragg grating (FBG) are exploited as sensing probes for simultaneous measurement of radiation dose and strain. The output power and the lasing wavelength of the proposed EDF laser are changed by increasing the radiation dose and strain, respectively. The radiation and strain sensitivities were measured to be 8.4 dB/km•Gy and 0.81 pm/με, respectively.
