Continous Wave Operation of Tm2O3-Doped Germanate Glass Laser around 2 μm
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.
