Abstract A cladding-pumped Tm³⁺-doped fibre laser is carried out to generate continuous-wave output power up to 8.4W at approximately 2μm with a slope efficiency of 57% compared to the launched pump power. When the fibre is cooled by water, the slope efficiency increases greatly and the output laser spectrum has a blue shift.
