摘要：The novel concept of utilizing the second-order random fiber laser (RFL) to realize long-distance fiber-optic pointsensing systems is proposed. The sensing system consists of a pump laser, a fiber Bragg grating (FBG) at the pump side and 100km single mode fiber (SMF), and another FBG at the end of the SMF. The first FBG is used to enhance the lasing efficiency, and the second FBG is use as the remotely-located sensing head. The Bragg wavelengths of the two FBGs correspond to the first-order and the second-order random lasing spectrum, respectively. Its ability for remote temperature sensing is
