Abstract :
The dependence of threshold and slope efficiency on pump wavelength around 0.8 μm has been investigated for an Yb-sensitised fibre laser. Results confirm a wider choice of pump wavelength compared with unsensitised Er fibre. A 5 mW threshold and slope efficiency of 8.5% were observed for 820-830 nm pumping
