0.685 at 的详细偏振光谱特性。研究了直拉法生长的％Nd(3+):Sr(3)Y(2)(BO(3))(4)晶体的吸收截面、发射截面和荧光寿命。深入讨论了不同偏振方向光谱特性的各向异性。由于其内部无序晶格，Nd(3+)的吸收和发射光谱不均匀展宽。此外，还首次演示了1.06μm的连续激光操作。实现了905 mW的最大输出功率，相应的光学转换效率为10.8%，斜率效率为12.8%。
Detailed polarized spectral properties of a 0.685 at. % Nd(3+):Sr(3)Y(2)(BO(3))(4) crystal grown by the Czochralski method have been investigated, including the absorption cross section, the emission cross section, and the fluorescence lifetime. The anisotropy of the spectral properties in different polarized directions was discussed thoroughly. The absorption and emission spectra of Nd(3+) are found to be inhomogeneously broadened due to its internal disordered lattice. Additionally, the CW laser operation at 1.06 μm was also demonstrated for the first time. The maximum output power of 905 mW was achieved, with corresponding optical conversion efficiency of 10.8% and slope efficiency of 12.8%.
