Growth and spectral properties of Tm3+-doped Sr3Y(BO3)3 crystal

This paper reports the growth and spectral properties of Tm3+:Sr3Y(BO3)3 crystals. A Tm3+:Sr3Y(BO3)3 crystal with dimension of Θ27 × 36 mm3 has been grown by the Czochralski method. The spectral properties of Tm3+:Sr3Y(BO3)3 crystal were investigated. Based on the Judd–Ofelt theory the spectral parameters were calculated. The emission cross-section is 4.682 × 10−21 cm2 at about 1890 nm. The above results suggest Tm3+:Sr3Y(BO3)3 crystal as a potential infrared laser crystal.
