Abstract A novel Dy:LuAG transparent ceramic was fabricated by a solid-state method, and it has the potential to be used as the gain medium of yellow laser generated by blue LD pumping. The spectroscopic parameters were determined by the Judd-Ofelt theory, and Ω2, Ω4, Ω6 were calculated to be 0.57×10−20 cm2, 1.44×10−20 cm2, 0.68×10−20 cm2, respectively. An intense yellow emission band, corresponding to the 4F9/2 →6H13/2 transition located at 581 nm, was observed in the visible region. The non-exponential curve was fitted to the Inokuti–Hirayama model to understand the energy-transfer mechanism. The fluorescence lifetime of the 4F9/2 level was about 339 μs, and the quantum efficiency was 21.7%.

一种新型掺镱 Lu3Al5O12 透明陶瓷在黄色激光产生中的潜在应用研究

摘要 采用固态方法制备了一种新型Dy:LuAG透明陶瓷，具有作为蓝色LD泵浦产生的黄色激光增益介质的潜力。光谱参数由Judd-Ofelt理论确定，计算得到的Ω2、Ω4、Ω6分别为0.57×10-20 cm2、1.44×10-20 cm2、0.68×10-20 cm2。在可见光区观察到一个强烈的黄色发射带，对应于位于 581 nm 的 4F9/2 →6H13/2 跃迁。非指数曲线拟合 Inokuti-Hirayama 模型以了解能量转移机制。4F9/2能级的荧光寿命约为339 μs，量子效率为21.7%。
