摘要
A cladding-pumped Tm^3+-doped fibre laser is carried out to generate continuous-wave output power up to 8.4 W at approximately 2 μm 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.
