为了实现激光二极管阵列(LDA)的高亮度光纤耦合输出,设计了一套简单有效的光束整形系统.首先采用快慢轴准直透镜压缩LDA的发散角,然后采用双平行平面反射镜光束整形装置,将压缩后的LDA慢轴方向的光束分为4束(也可以根据需要分为任意多束),并将4束子光束在快轴方向重新排列,最后通过聚焦系统,将整形后的光束耦合进入芯径600 μm,数值孔径0.37的光纤.实验测得双平行平面反射镜整形装置的效率为98.87%,系统的整体效率为77.2%.该整形系统设计简单,效牢高,具有很高的应用价值. |

In order to achieve high brightness fiber-coupled output of diode laser array, a simple but efficient system was designed. Firstly, the output beam from a laser diode arrays (LDA) was collimated by fast and slow axis collimation module. Secondly, the collimated beam in the slow axis was divided into 4 parts (any other amount of the divided parts if needed) by the beam-shaping set of two parallel plane mirrors, and then reordered in the fast axis. Finally, the shaped beams were focused into a fiber (φ600 μm, NA = 0. 37) by a focusing lens. The beam-shaping efficiency was 98. 87% , and the total system efficiency was 77.2 % . This beam-shaping system is simple but effective and useful. |
