摘要：

We have demonstrated dual-wavelength continuous-wave oscillation at 3 and 2 mu m with a He-doped ZrF4-BaF2-LaF3-AlF3-NaF fluoride-glass fiber laser by use of a cascade oscillation scheme. We have shown that the fiber laser operates with a high slope efficiency of 52% (at 3 and 2 mu m) with respect to the absorbed pump power. With a 6.5-m-long fiber we achieved an output power of 90 mW at each of the wavelengths that was limited only by the pump power, and the 3-mu m output power is to our knowledge higher than any previously reported level with 3-mu m Ho3+-doped fiber lasers.
