A random fiber laser does not need a traditional resonant cavity and only uses the multiple scattering of disordered media to provide feedback to achieve laser output. Therefore, it has the advantages of a simple structure, narrow linewidth, and low noise and is particularly suitable for fiber optic sensors. This paper provides an introduction to the categories and corresponding principles of random fiber lasers. The research progress of random fiber lasers in the sensing field in recent years, including various aspects of random fiber lasers as low-noise light sources or sensitive elements for fiber sensing systems, is the main focus. Finally, the future development trend of random fiber lasers for optical fiber sensors is explored.
随机光纤激光器不需要传统的谐振腔，仅利用无序介质的多重散射来提供反馈以实现激光输出。因此，它具有结构简单、线宽窄和噪声低的优点，特别适用于光纤传感器。本文介绍了随机光纤激光器的类别及相应原理。近年来随机光纤激光器在传感领域的研究进展，包括随机光纤激光器作为光纤传感系统的低噪声光源或敏感元件的各个方面，是主要关注点。最后，探讨了用于光纤传感器的随机光纤激光器的未来发展趋势。
