摘要：
A 1.47 mum band optical amplifier using Tm3+ doped fluoride fibre pumped by a 1.064 mum laser was demonstrated. A small signal gain of 25 dB and a saturated output power of over +10 dBm were observed at 1.470 mum for a pump power of 450 mW. The amplification bandwidth was approximately 65 nm from 1.440 to 1.505 mum.
