Key Points

To demonstrate a multiplexed fiber laser strain sensor system utilizing multiple fiber Bragg gratings as cavity feedback elements.
Configured a fiber laser cavity incorporating multiple fiber Bragg grating sensors as wavelength-selective feedback elements.
Tuned an intracavity wavelength-selective optical filter across the laser gain bandwidth to sequentially induce lasing at each sensor's specific Bragg wavelength.
Demonstrated successful selective lasing and strain interrogation in a four-sensor multiplexed system.
Tracked strain-induced shifts in Bragg wavelengths by monitoring emission wavelength changes corresponding to each feedback sensor during filter tuning.
