Cladding-Pumped Tm3+-Doped Large-Mode-Area Fibre Laser Highly Efficient Output at Approximately 2μm
-
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.
