摘 要: | 基于ZEMAX模拟了一组多光束半导体激光器的光纤耦合模块,采用14支波长为808 nm的输出功率为60 W的线列阵激光二极管作为耦合光源,采用偏振技术实现多光路的合束,最终耦合进入芯径400μm,NA为0.22的光纤中,最终输出功率超800 W,耦合效率达97%,实现了高效耦合,并对光纤对接过程中的耦合效率进行了分析。

Abstract: | The paper simulate the actual situation of fiber coupling of multiple beam semiconductor based on ZEMAX, using fourteen pieces of mini-bar that its output power is 60W are arranged in two stack arrays as laser source by po-larization multiplexing. The beam could be coupled into the fiber of 400μm core diameter with 0.22 numerical aperture. The output power is more than 800W and the coupling efficiency is about 97%. It is analysed that the system coupling efficiency can be affected by alignment error of fiber and optical elements. |
