Abstract

This letter presents the development of a high-resolution all-fiber strain sensing system using a narrow linewidth Brillouin-random laser (BRL) in conjunction with a fiber Bragg grating (FBG). The so-called BRL-FBG sensor system is based on a Brillouin fiber laser with a linewidth narrowed by a random laser obtained with a nanoparticle (NP) doped optical fiber, especially manufactured for a higher Rayleigh scattering. The BRL results indicated a 74.68% reduction of the laser linewidth when the NP-doped fiber is used. Furthermore, the laser presented a power stability of 92.36%. Then, the BRL signal is fed to an FBG, subjected to small axial strain variation and the convolution between both signals result in the reflected optical power variations as a function applied strain, where a $0.05 \mu \epsilon$ strain sensing resolution is obtained. Thus, the proposed system can be employed on the high-resolution sensing of different physical parameters with potentially high acquisition frequency.

用于全光纤高分辨率传感的布里渊随机激光和光纤布拉格光栅
本文介绍了一种高分辨率全光纤应变传感系统的开发,该系统使用窄线宽布里渊随机激光器(BRL)与光纤布拉格光栅(FBG)相结合。所谓的BRL-FBG传感器系统是基于布里渊光纤激光器,其线宽由掺杂纳米粒子(NP)的光纤获得的随机激光器变窄,特别是为更高的瑞利散射而制造的。BRL结果为74.68% reduction of the laser linewidth when the NP-doped fiber is used. Furthermore, the laser presented a power stability of 92.36%. Then, the BRL signal is fed to an FBG, subjected to small axial strain variation and the convolution between both signals result in the reflected optical power variations as a function applied strain, where a $0.05 \mu \epsilon$ strain sensing resolution is obtained. Thus, the proposed system can be employed on the high-resolution sensing of different physical parameters with potentially high acquisition frequency.
