The difference in fabrication was the application of a suspension of aluminum oxide nanoparticles of defined size instead of a conventional chloride-containing solution. Samples of thulium-doped silica fibers having nearly identical chemical composition and waveguiding properties were fabricated. The sample fabricated by means of the nanoparticle-doping method exhibited longer lifetime, reflecting other observations and the trend already observed with the fibers doped with erbium and aluminum nanoparticles. The fiber fabricated by means of the nanoparticle-doping method exhibited a lower lasing threshold (by similar to 20%) and higher slope efficiency (by similar to 5% rel.). All these observed differences are not extensive and deserve more in-depth research, they may imply a positive influence of the nanoparticle approach on properties of rare-earth-doped fibers for fiber lasers Pracoviště Ústav fotoniky a elektroniky Kontakt Petr Vacek, vacek@ufe.cz, Tel.: 266 773 413, 266 773 438, 266 773 488 Rok sběru 2020 Elektronická adresa http://journals.pan.pl/dlibra/publication/130883/edition/114308/content
