Fiber lasers are in focus of intense research thanks to their high efficiency, beam quality, high average power, compactness and other advantages that are beneficial for increasing scope of applications including space ones. Silica optical fibers doped with rare-earth ions represent hearts of these lasers. Knowledge of stability of their optical properties including their behavior under extreme space conditions is important for wide employment of fiber lasers. Attention will be focused on investigation of glassy materials of various matrices doped with thulium or holmium emitting at 2 um spectral region and co-doped with other elements or oxides aiming at enhancement of radiation resistivity of these materials.Glassforming, refractive index, spectroscopic, mechanical properties and radiation resistivity of the prepared materials will be studied. The achieved results leading to forecast of suitable materials in form of radiation resistive optical fibers together with methods of their preparation will be verified later by testing in fiber lasers.
