In 1961 Elias Snitzer introduced the concept of the laser with rare-earth doped optical fiber as an active medium. This, together with the following Snitzer’s idea of double-clad active fiber, has started the era of fiber laser technology and resulted in dynamic development of a new class of coherent radiation sources offering excellent properties – laser action at single spatial mode (M2 parameter close to unity) combined with enormously high output powers (of order of kWs). These unique advantages result from this specific geometry of active medium, which offers not only easiness of obtaining single transverse mode operation but also excellent heat dissipation and, due to waveguide effect, a possibility of using the active media of almost any length while maintaining a compact size of the entire device. In recent years, fiber laser-based systems have dominated the market of solid-state lasers, finding numerous applications in industrial systems for materials’ processing (cutting, welding, hardening, etc.), medical systems and laser weapon systems as well. It should be emphasized here, that although there is a number of fiber lasers manufacturers, only a few centers dispose of technological competencies that allow the production of active fibers of appropriate properties. This work will summarize the results of several years of our efforts on mastering the technology of manufacturing active optical fibers applicable to laser systems. The fundamentals of the technology will be presented together with the results of the spectroscopic characterization of developed fibers and first laser experiments with Polish active fibers doped with ytterbium and thulium ions, developed in the Laboratory of Fiber Optic Technology at the Faculty of Chemistry of Maria Curie-Skłodowska University, Lublin, Poland. Both spectroscopic and laser properties of developed preforms and active fibers will be compared with properties of samples available from commercial suppliers.
