To date, most research on rare earth doped optical fibre amplifiers has been directed towards developing high gain amplifiers in the second and third telecommunications windows at 1.3µm and 1.55µm respectively. In this paper we describe a Tm3+-doped fluorozirconate fibre amplifier pumped at 785nm and giving 20dB gain at 806nm in the first telecommunications window.
