Continous Wave Operation of Tm2O3-Doped Germanate Glass Laser around 2 μm
摘要
报道了一种Tm2O3掺杂的新型FGe玻璃连续激光运转。实验中增益介质采用未镀膜的掺杂摩尔分数为1%的Tm2O3的GeO2-Ga2O3-BaF2-MO/F2 (FGe)玻璃,在波长790 nm的钛宝石激光抽运下,使用两种输出耦合镜分别实现了连续激光振荡。在3%输出耦合镜下得到了83 mW的激光输出,斜率效率为13.7%,光光转换效率为8.8%,激光的中心波长为1968 nm。
Abstract
A continuous-wave (CW) Tm2O3-doped FGe glass laser is demonstrated. An uncoated one percent of mole fraction Tm2O3-doped GeO2-Ga2O3-BaF2-MO/F2 (FGe) glass is employed as the laser medium. Pumped with a Tisapphire laser at 790 nm, CW laser is realized using two kinds of output couplers (OC). Under the 3% OC, output power of 83 mW is obtained, corresponding to a slope efficiency of 13.7%, and the optical conversion efficiency is 8.8%. The measured central wavelength is 1968 nm.
