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 1905000 nm at room temperature. Excitation and luminescence spectra were also recorded at room temperature with a JOBIN-YVON spectrofluorimeter using a diode laser POLAROID 4300, 980 nm, 1 W as an excitation source. The measurements of the lifetime of the Er3 ions in the upper laser level sup 4 I sub 132 of the samples were made by the direct method with pulse excitation. We present also the results 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.
