| 摘 要： | 与通常的双包层光纤激光器不同，光纤前端面与二色镜拉开一个小的距离，构成了Fabry-Perot滤波器。理论分析了Fabry-Perot滤波器效应。通过调节光纤前端面与二色镜之间的距离，实现了掺Yb3+双包层光纤激光器的窄线宽激光输出，中心波长为1 082.79 nm，谱线宽度为0.14 nm，斜率效率为20%，最大输出功率为0.62 W。

| Abstract: | Different from a traditional double clad fiber laser, the front end of the double clad fiber is separated from the dichroic mirror which forms a Fabry-Perot filter. The efficiency of Fabry-Perot filter is analyzed theoretically. By adjusting the distance between the mirror and the end of the fiber, a novel Yb 3+ doped double clad fiber laser with narrow line width and single mode is presented. In the experiment, the laser with an output power of 0.62 W and a slope efficiency of 20% is obtained. The line width at central wavelength of 1 082.79 nm is only 0.14 nm. |
