摘要：
A 1.064-mu m band upconversion pumped Tm3+-doped fluoride fiber amplifier and a laser both operating at 1.47 mu m are investigated in detail, The two devices are based on the F-3(4) --> H-3(4) transition in a trivalent thulium ion, which is a self-terminating system, When pumped at 1.064 mu m, the amplifier has a gain of over 10 dB from 1,44 to 1.51 mu m and a low-noise characteristic, Also, the fiber laser generates a high-output power of over 100 mW with a slope efficiency of 59% at around 1.47 mu m. These levels of performance will be important for optical communication systems.
