External optical feedback effects due to reflection, Rayleigh backscattering and coherent Rayleigh backscattering in fiber distributed feedback (DFB) fiber laser sensor system have been investigated. If the feedback intensity exceeds critical amount, excess noise would be induced in the demodulator. The maximum tolerable intensity back-reflection coefficient Rc and backscattering coefficient Sc into a fiber DFB laser with lead fiber length from 1 m to 37.5 k…查看全部>>
