论文摘要
我们报告了两个c $ _ {1} $对称中心的参数化水晶模型的开发和应用。进行高分辨率的zeeman和温度依赖性吸收光谱，以获取必要的实验数据。除了地面之外，获得的数据（$^{4} $ i $ _ {15/2} $ z $ _ {1} $）状态并退出（$^{4} $ i $ _ {13/2} $ y $ y $ y $ _ {1} $）州Zeeman和State Zeeman和State Zeeman and HyperFine结构er $^{3+} $：y $ _ {2} $ sio $ _ {5} $ system。 We demonstrate that it is possible to account for the electronic, magnetic and hyperfine structure of the full 4f$^{11}$ configuration of Er$^{3+}$:Y$_{2}$SiO$_{5}$ and further, that it is possible to predict both optical polarization behavior and high magnetic field hyperfine structure of transitions in the 1.5 $μ$m telecommunications band.
We report on the development and application of a parametrized crystal-field model for both C$_{1}$ symmetry centers in trivalent erbium-doped Y$_{2}$SiO$_{5}$. High resolution Zeeman and temperature dependent absorption spectroscopy was performed to acquire the necessary experimental data. The obtained data, in addition to the ground ($^{4}$I$_{15/2}$Z$_{1}$) state and exited ($^{4}$I$_{13/2}$Y$_{1}$) state Zeeman and hyperfine structure, was simultaneously fitted in order to refine an existing crystal-field interpretation of the Er$^{3+}$:Y$_{2}$SiO$_{5}$ system. We demonstrate that it is possible to account for the electronic, magnetic and hyperfine structure of the full 4f$^{11}$ configuration of Er$^{3+}$:Y$_{2}$SiO$_{5}$ and further, that it is possible to predict both optical polarization behavior and high magnetic field hyperfine structure of transitions in the 1.5 $μ$m telecommunications band.
