Recently, in virtue of the develop of the semiconductor laser and the doped laser materials with rare-earth ions, the up-conversion laser with resonant pump has became a scientific subject in great demand. The doped oxyfluoride glass ceramic with rare-earth ions is a very excellent material, its optical property and chemical stability are outstanding. So, absorption spectrum of Er3+ in Fluoroxide glass ceramic was measured, and intensity parameters omega lambda were calculated using Judd-Oflet theory. Some predicted spectroscopic parameters of the excited states, like the spontaneous radiative transition rate, branching ratio and integrated emission cross section were given.
近年来,由于半导体激光器和稀土离子掺杂激光材料的发展,共振泵浦上转换激光器已成为一个急需的科学课题。稀土离子掺杂的氟氧化物玻璃陶瓷是一种非常优异的材料,其光学性能和化学稳定性都很突出。因此,测量了氟氧化物玻璃陶瓷中Er3+的吸收光谱,并采用Judd-Oflet理论计算了强度参数ωλ。给出了一些激发态的预测光谱参数,如自发辐射跃迁速率、分支比和积分发射截面。
