| 摘 要： | 针对光纤激光相干组柬方式对于相干合成效率的重要影响,文章对填充因子如何影响相干合成效果进行了深入的理论计算和仿真分析.同时,考虑相干合成中各路光束光轴之间无法避免指向误差,因此又详细计算和仿真了光轴倾斜度对于相干效率的影响.基于此探索性地提出了复合离轴扩束聚焦的组束方案.建立了理论模型,得出了焦距、束腰、峰值功率之间的...

| Abstract: | The arrangement of laser beams influences the efficiency of coherence.The article analyses how filling factor influences the efficiency of coherence based on theories calculation and simulation.In the meantime,the article analyses how the orientation error caused by each beam's installation error influences the efficiency of coherence,and these installation errors are hard to be avoided whatever in experiments or ultimate engineering practice.According to the result of analysis,a project tentatively named o... |
