【 摘 要 】

We report on the development and application of a parametrized crystal-field model for both C-1 symmetry centers in trivalent erbium-doped Y2SiO5. High-resolution Zeeman and temperature dependent absorption spectroscopy was performed to acquire the necessary experimental data. The obtained data, in addition to the ground (I-4(15/2) Z(1)) state and exited (I-4(13/2) Y-1) state Zeeman and hyperfine structure, were simultaneously fitted in order to refine an existing crystal-field interpretation of the Er3+:Y2SiO5 system. We demonstrate that it is possible to account for the electronic, magnetic, and hyperfine structure of the full 4f(11) configuration of Er3+:Y2SiO5 and further, that it is possible to predict both optical polarization behavior and high magnetic field hyperfine structure of transitions in the 1.5-mu m telecommunications band.
