Spectra properties of Yb³⁺, Er³⁺: Sc₂SiO₅ crystal

The influence of Er³⁺ ions on the spectra of Yb³⁺, Er³⁺:Sc₂SiO₅ (SSO) single crystal, which was obtained by Czochralski (Cz) method, is discussed. The absorption coefficient at 980 nm was 13.36 cm^-1 with a peak absorption cross-section of 1.46×10^-20 cm². The emission cross-sections at 1034 nm and 1062 nm were 5.5×10^-21 cm² and 4.9×10^-21 cm², respectively. The fluorescence lifetime was estimated as 1.24 ms at 1061 nm. The mechanical properties of SSO single crystal were also presented.
