橙光Bi2Se3被动调Q Pr:ZBLAN全光纤脉冲激光器理论与实验研究

Abstract

可见光脉冲激光器在远距离探测、医疗和通信领域有着重要的应用。相比非线性倍频方法得到可见光，利用掺杂稀土离子光纤激射可见光，具有结构紧凑、简单和高效的优点。Pr3+离子是唯一在室温下可激射多种可见光波长的稀土离子。可见光波段在普通石英光纤中有较大的传输损耗，而ZBLAN光纤因为声子能量很低，仅为580cm-1，且在可见光波段传输损耗小（

Visible pulse lasers play an important role in remote sensing, medicine, and communications. Compared to second-harmonic visible lasers, rare-earth-doped visible fiber lasers offer compact construction, are maintenance-free, and have high efficiency. Pr3+ is the only rare earth ion that emit multi-wavelength in visible range at room temperature. Furthermore, ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) fiber p...
