论文摘要
由于光学轨道角动量（OAM）出现了，因此绿色绿洲束的生成和操纵的进步不断影响着有趣的应用，包括光学通信，光学镊子和遥感。为了实现高功率和快速可切换的OAM梁的产生，纤维激光器的连贯结合提供了一种有希望的方法。在此贡献中，我们全面研究了相干纤维激光阵列系统，用于根据设计注意事项和性能分析来构建OAM光束。提出并引入了激光阵列系统的性能指标和评估方法。因此，评估了激光阵列系统的主要部分的影响，即高功率激光源，发射阵列配置和动态控制系统，对相干组合的OAM梁的性能进行评估，从而揭示了触发因素的系统耐受性，并为系统设计和优化提供了指导。这项工作可以提供有益的参考，以实现具有光纤激光阵列的空间结构高功率，快速可切换的OAM光束。
Since the advent of optical orbital angular momentum (OAM), advances in the generation and manipulation of OAM beams have continuously impacted on intriguing applications including optical communication, optical tweezers, and remote sensing. To realize the generation of high-power and fast switchable OAM beams, coherent combining of fiber lasers offers a promising way. Here in this contribution, we comprehensively investigate the coherent fiber laser array system for structuring OAM beams in terms of the design considerations and performance analysis. The performance metric and evaluation method of the laser array system are presented and introduced. Accordingly, the effect of the main sections of the laser array system, namely the high-power laser sources, emitting array configuration, and dynamic control system, on the performance of the output coherently combined OAM beams is evaluated, which reveals the system tolerance of perturbative factors and provides the guidance on system design and optimization. This work could provide beneficial reference on the practical implementation of spatially structuring high-power, fast switchable OAM beams with fiber laser arrays.
