Of late, fiber lasers compared to other kinds of lasers benefit from their all-fiber design, leading to a compact, robust, and well thermally manageable device. Particularly, thulium- and holmium-doped fiber lasers are the first choice in fiber lasers emitting light around 2 mu m. In this paper, we give an overview of our recent results in the research on thulium- and holmium-doped optical fibers, fiber lasers, and related research topics in the 2-mu m spectral range. In particular, we present, to our knowledge, the first results of improvement of pump absorption in double-clad fibers thanks to the fiber twist frozen during drawing. Finally, a brief demonstration of material processing by thulium all-fiber laser operating at 2 mu m is presented Workplace Institute of Radio Engineering and Electronics Contact Petr Vacek, vacek@ufe.cz, Tel.: 266 773 413, 266 773 438, 266 773 488 Year of Publishing 2021 Electronic address https://doi.org/10.3390/ma13225177
