Sensors, Vol. 20, Pages 6122: Advances in Random Fiber Lasers and Their Sensing Application Sensors doi: 10.3390/s20216122 Authors: Hong Chen Shaohua Gao Mingjiang Zhang Jianzhong Zhang Lijun Qiao Tao Wang Fei Gao Xinxin Hu Shichuan Li Yicheng Zhu Compared with conventional laser, random laser (RL) has no resonant cavity, reducing the requirement of cavity design. In recent years, the random fiber laser (RFL), a novel kind of RL, has made great progress in theories and experiments. The RFL has a simpler structure, a more flexible design, and higher reliability. It has valuable applications for earth sciences, biological life sciences, and national defense security, due to these unique properties. This paper reviews the development of RFLs in the last decade, including their configurations based on various optical fibers and their output properties, especially the method of control. Moreover, we also introduce their applications in the optical fiber sensing system, which is a very important and practical orientation to study. Finally, this paper presents the prospects of RFLs.
