| Abstract: | 0.54 mum band amplification using Tb3+-doped fluoride fibre is demonstrated. Spectroscopic properties of Tb3+-doped fluoride glass are clarified. A gain of 5.3 dB has been obtained in a 1 wt.% Tb3+-doped fluoride fibre for a signal power of -30 dBm by forward pumping at a wavelength of 0.488 mum with power of 100 mW |
