Abstract
A 1.9 mum Tm-doped silica fibre laser pumped at 1.57 mum is described. The pump source is an Er-doped fibre laser pumped by a 0.98 mum Ti:sa pphire laser. The threshold pump power is 95 mW and the slope efficien cy is as high as 71%. A maximum output power of 21 mW was obtained at a launched pump power of 127 mW. The oscillation wavelength can be tun ed from 1.84 to 1.90 mum by changing the length of the Tm-doped fibre.
