## Abstract A novel interrogation of fiber Bragg grating (FBG) in a strain sensor, which is based on Erβdoped fiber laser's transient regime, is reported. The applied strain on FBG changes the laser cavity loss, which in turn modifies the laser's transient regime. The strain value can be obtained b
