Abstract :
Reports for the first time laser emission at 2.3 μm from a thulium-doped fluorozirconate fibre pumped by a pulsed alexandrite laser at 0.786 μm. Threshold occurs at 25 μJ incident on the focusing lens. This wavelength is in the 2-3 μm ultra-low loss region of fluorozirconate fibres. Further improvement is expected to result in Cw operation using diode laser pumping
