摘要
基于对双包层光纤的内包层结构、掺杂浓度、剖面折射率分布、外包层的背底损耗等因素对泵浦光吸收效率的影响进行分析的基础上,对掺Yb3+双包层光纤内包层直径对泵浦光的吸收长度和泵浦效率进行了理论模拟。采用半导体激光二极管光纤模块作为泵浦源,采用梅花瓣型双包层光纤与光纤光栅元件连接制作了全光纤结构的光纤激光器,实验获得了 6.02 W单模光纤激光器,中心波长为1 080 nm,半高宽为0.11 nm,斜率效率为1.7 W/A。
The pumping efficiency and absorption length of pumping source for Yb-doped double cladding fiber are theoretically simulated based on the analyses of the effects of inner cladding structure, doping concentration, paraboloid index profile and background loss of outer cladding on pumping absorption efficiencies. All fiber laser uses semiconductor laser diode as pumping source, and the connection of quincunx double cladding fiber and fiber grating as resonance cavity. Single mode fiber lasers with 6.02 W single mode output, central wavelength of 1080 nm, FWHM of 0.11 nm and slope efficiency of 1.7 W/A are realized.
