Abstract:

An Nd³⁺ :Li₃Ba₂Y₃(WO₄)₈ crystal with dimensions up to 32 × 20 × 14 mm has been grown by the top seed solution growth method. The spectral characterisation of Nd³⁺ :Li₃Ba₂Y₃(WO₄)₈ crystal was investigated. The investigated results show that Nd³⁺ :Li₃Ba₂Y₃(WO₄)₈ crystal has a broad absorption band with full width at half maximum (FWHM) of ?9 nm at 805 nm. The absorption cross-sections are 10·12 × 10^–20 cm² for E//Y, 2·33 × 10^–20 cm² for E//X and 3·69 × 10^–20 cm² for E//Z respectively. The emission cross sections are 4·45 × 10^–20 cm² at 1065 nm for E//X, 15·51 × 10^–20 cm² at 1061 nm for E//Y and 6·67 × 10^–20 cm² at 1061 nm for E//Z respectively. The quantum efficiency ? is 93·7%. These results suggest that Nd³⁺ :Li₃Ba₂Y₃(WO₄)₈ crystal may be regarded as a new high efficiency laser crystal material.
