摘要：

The gain characteristics of a 1.4-mu m-band thulium-holmium doped ZBLYAN fiber amplifier are described, Signal gain is obtained over the whole 1.4-mu m band for a pump power level of 73.5 mW, A maximum signal gain of 18 dB is achieved at a signal wavelength of 1.46 mu m for a pump power of 150 mW at 0.79 mu m. The noise figure is 5.6 dB in the signal wavelength region from 1.45-1.50 mu m. From a comparison of the gain characteristics of thulium-holmium-doped ZBLYAN fibers and thulium-doped ZBLYAN fibers, it is proved that holmium ions play an effective role in increasing the gain and widening the gain spectrum.
