【摘要】 报道了采用国产双包层掺镱光纤搭建的高功率光纤激光器。此光纤激光器采用中国电子科技集团公司第四十六研究所最新研制的20/400双包层掺镱光纤,激光器采用谐振腔振荡方式输出,激光器中心波长为1080 nm,最高输出激光功率为758 W,输出光斑直径6~8 mm,接近准单模输出,光束β因子为1.3。电光转换效率36.7%,光-光转换效率71%,经过32 h的满功率激光输出,平均输出功率波动范围小于2%。更多还原

【Abstract】 An all-fiber high-power fiber laser with home-made 20/400 double cladding Yb-doped fiber( DCF) was reported. The laser output uses resonant cavity mode,and its central wavelength is 1080 nm,the maximum output power is 758 W,the output spot diameter is 6 ~ 8 mm,the β factor is 1. 3; the electro-optical conversion efficiency is 36. 7%,and optical-to-optical efficiency is 71%. After 32 hours of laser output,the fluctuation range of average output power is less than 2%.更多还原
