Thulium-doped fluorozirconate fibre can be used as an efficient amplifier over the wavelength range 800 - 815nm in the first telecommunications window. A small-signal gain of 23dB has been achieved at 805nm with 50mW of launched pump power at 780nm. The fibre used for this demonstration had a core diameter of 3.5µm, numerical aperture 0.16 and thulium ion concentration 800ppm by weight. The background loss of the fibre was measured to be less than 0.1dB/m. These results suggest that a high gain 800nm amplifier employing an AlGaAs diode-pumped thulium-doped fluorozirconate fibre can now be made.
