Abstract :
A thulium doped fluorozirconate fibre laser operating continuous-wave at wavelengths around 810 nm when pumped at 780 nm is reported. A slope efficiency of 15% with respect to incident pump power and a maximum output of 125 mW was achieved. This transition has the potential for laser diode pumping and with the output also being in the AlGaAs diode wavelength range there exist interesting possibilities for extending the versatility of such sources.
