摘　　要：分析了双包层光纤内包层及纤芯偏移对光纤熔接的影响。根据分析结果,针对主振荡功率放大全光纤化激光系统中关键熔接点,提出了合理的光纤熔接方案。在种子光功率为533W,抽运光功率为1.16kW时,全光纤化激光系统实现了1509W放大激光功率输出,放大器的斜率效率为87.3%,中心波长为1080nm,光束质量因子M2=1.46。The influence of the double-clad fiber inner-cladding and core axial deviation on fiber splicing is theoretically analyzed. Based on the analysis of the results , in the master oscillator power amplifier laser system, a reasonable method to splice the key points is proposed. The 1509 W amplified power in all-fiber laser system at 1080 nm is achieved with a 533 W seed laser and a 1.16 kW pump power. The slope efficiency of the amplifier is up to 87.3% with central wavelength of 1080 nm, and the beam quality of the output laser is M2=1.46.
