Czochralski growth of six Yb-doped double borate and silicate laser materials

摘要

New Yb-doped oxides have been grown by the Czochralski method. They include borates such as Ca_3Y_2(BO_3)_4 (CYB), Ca_3Gd_2(BO_3)_4 (CaGB), Sr_3Y(BO_3)_3 (SrYBO) and Ba_3Lu(BO_3)_3 (BluB) as well as the silicates Y_2SiO_5 (YSO), Ca_2Al_2SiO_7(CAS) and SrY_4(SiO_4)_3O (SYS). Successful Czochralski growth is reported for the first time in th case of SrYBO. Scattering center free CAS single crystals were obtained as welo.
