Random Fiber Lasers

A multimode-fiber-mediated random fiber laser with 100+ watt output power was demonstrated for speckle-free imaging, as presented by Shanshan Wang, Weili Zhang, Yunjiang Rao, and co-workers in article number 2100390. A random laser combined with multimode fiber provides a powerful platform to realize advanced fiber lasers with controllable spatial characteristics, which is of great significance for applications of imaging and sensing.
