We present the preparation and characterization of holmium-doped silica-based optical fibers for fiber lasers operating around two micrometers. The fibers were prepared by a modified chemical vapor deposition process and co-doped with aluminum oxide. Alumina was doped with the use of two different methods - solution doping and nanoparticle doping. Prepared optical preforms and fibers were characterized according to their optical, spectral and laser properties. It was observed that the doping by alumina nanoparticles improve a fluorescence lifetime and laser characteristics such as laser threshold and slope efficiency. The comparison of both doping methods is presented and results are discussed
