Abstract

The present work focuses on the spectroscopic and laser properties of Nd³⁺ in a Li₂O–BaO–Al₂O₃–P₂O₅ aluminophosphate glass which includes Judd-Ofelt calculation, stimulated emission cross-section of the ⁴F_3/2 → ⁴I_11/2 emission laser transition, lifetime of the ⁴F_3/2 state and quantum efficiency. Site-selective laser spectroscopy and stimulated emission under selective excitation has been performed to determine the crystal field inhomogeneity at the Nd³⁺ site together with its broadening effect on the spontaneous and laser emissions. However, a much narrowed laser emission has been achieved by using an intracavity tilting plate which acts as a tunable optical filter to adjust the laser wavelength.

晶体场不均匀性对掺杂 Nd3+ 的 Li2O-BaO-Al2O3-P2O5 玻璃自发辐射和激光调谐发射的影响

本研究的重点是 Li2O-BaO-Al2O3-P2O5 磷化铝玻璃中 Nd3+ 的光谱和激光特性，包括 Judd-Ofelt 计算、4F3/2 → 4I11/2 发射激光转变的激发发射截面、4F3/2 状态的寿命和量子效率。为了确定 Nd3+ 位点的晶体场不均匀性及其对自发和激光发射的增宽效应，我们进行了位点选择性激光光谱分析和选择性激发下的受激发射。不过，通过使用腔内倾斜板（可用作调节激光波长的可调谐光学滤波器），激光发射范围大大缩小。
