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.
与传统激光相比，随机激光（RL）没有谐振腔，降低了对腔设计的要求。近年来，新型 RL 之一的随机光纤激光（RFL）在理论和实验方面都取得了很大的进展。RFL 结构更简单，设计更灵活，可靠性更高，由于这些独特的性质，在地球科学、生物生命科学和国防安全方面具有有价值的应用。本文回顾了过去十年中 RFL 的发展，包括基于各种光纤的配置及其输出特性，特别是控制方法。此外，我们还介绍了它们在光纤传感系统中的应用，这是一个非常重要和实用的研究方向。最后，本文提出了 RFL 的前景。
