Paper Abstract

The results of examinations of spectroscopic properties and generation parameters of new active media, i.e., Er3+ and Yb3+ doped YAG crystals are given. Erbium and ytterbium doped YAG single crystals were obtained by the Czochralski method. The spectral properties and laser characteristics were investigated. Absorption spectra of Er3+ and Yb3+-doped active media were measured in the spectral range 190 divided by 5000 nm at room temperature. Excitation and luminescence spectra were also recorded at room temperature with a JOBIN-YVON spectrofluorimeter using a diode laser as an excitation source. The measurements of the lifetime of the Er3+ ions in the upper laser level of the samples were made by the direct method with pulse excitation. We present also the result of investigations on spectroscopic properties and non-linear absorption effect in YAG:Co2+ crystal-new absorber used for the systems generating giant-pulse radiation at 1.5 micrometers .
