Paper Abstract

Rare-earth doped SrLaGa3O7 single crystal are promising laser materials. Also crystal doped with Ho3+ ions could be used as efficient laser in visible and near IR regions. Laser materials, generating in visible and IR regions, can be used for optical data recording in micro photolithography and in medicine. SrLaGa3O7 single crystal doped with 0.3, 1.5 and 2 at percent of Ho3+, respectively were grown by the Czochralski method with use of iridium crucible and after heater. According to EPMA measurements distribution coefficient of Ho3+ in SrLaGa3O7 was estimated to be k approximately equals 0.22. Optical absorption spectra in visible and IR regions were measured at 300K and 12K respectively. Optical quality of single crystals was checked by the use of computerized imaging spectropolarimeter and polariscopic measurements. Temperature dependence of capacitance and conductivity for different dopant concentrations were also measured.
