Growth and spectroscopic properties of Yb³⁺ doped BaGd₂ (MoO₄)₄ crystal

Abstract

Yb³⁺ doped BaGd₂(MoO₄)₄ crystal with dimension &phis20 × 25 mm has been grown using the Czochralski method. The absorption and emission spectra have been investigated at room temperature. The strongest absorption peak at 977 nm has a full width at half maximum of 6 nm, and the absorption cross-section σ _ab is 3·3 × 10⁻²⁰ cm² at 977 nm. The broad emission band with a peak at 1005 nm has a full width at half maximum of 45 nm. The fluorescence lifetime is 0·59 ms. It may be regarded as a potential solid state laser material for the diode laser pumping.
