| 摘 要： | Using a Tm^3＋-doped double-cladding silica fibre, we produce a maximum cw 2.2 W output at approximately 2μm. The highest achieved slope efficiency is 29.3% respect to the launched pump power. The lowest threshold is 1.85 W using the double pass pump method with the fibre length 2. 7m, which is the lowest reported threshold of cladding pump of the ^3H4 level. The fibre laser output peak wavelength ranges from 1.967μm to 2.018μm with cavity 1 （R1 = 1 and R2=0.04） and from 1.95μm to 1.99μm with cavity 2 （R1=0.04 and R2=0.04）, as the fibre length varies.
