摘　　要：A laser diode （LD） cladding-pumped cw Tm^3＋ -doped silica fibre amplifier is reported that provides up to 3 W output with the slope efficiency nearly 30%. The gain fibre is 27.5/400μm D-shaped Tm^3＋ -doped silica double- cladding fibre, and the input signal sources is an LD-pumped Tm^3＋：YAP lasing at 1.99μm. The measured amplified spectrum only stretches a little relative to the input signal spectrum. This is the first report to the authors＇ knowledge of general experimental investigation of cladding-pumped Tm^3＋ -doped fibre amplifier of high power cw at 1.99μm.A laser diode （LD） cladding-pumped cw Tm^3＋ -doped silica fibre amplifier is reported that provides up to 3 W output with the slope efficiency nearly 30%.
