摘　　要：A temperature sensor based on a switchable dual-wavelength fiber Bragg grating （FBG） laser with a semiconductor saturable absorber mirror （SESAM） is presented and demonstrated experimentally. The repetition rate of Q-switched pulses is -17 kHz. The results demonstrate that the measured temperature has good linearity to the wavelength spacing of the two lasing wavelengths and has a temperature sensitivity of 21 pm/℃ covering a range of-10--22 ℃. The ex- perimental results prove the feasibility of the proposed temperature sensor.
