| 摘 要： | The fundamental characteristics of Fabry-Perot-cavity continuous-wave Tm-Ho codoped silica fibre lasers pumped by a 1.18μm Raman fibre laser are presented. A maximum output power of 930mW at 1880nm is generated for a fibre length of 1 m from the transition of Tm^3 , with a slope efficiency of 32.4%. For a 3-m-long fibre, the maximum output power decreases to 650 mW at 1960 nm due to the laser emission from Ho^3 with a lower slope efficiency of 25%, which clearly shows the effective energy transfer from Tm^3 to Ho^3 . The wavelength redshifting of the laser emission originates from the transition competition and the emission cross section difference between Tm^3 and Ho^3 .
