Varied embodiments of a laser-based machine tool, and techniques for controlling the same are provided. Some embodiments relate to techniques to facilitate uniform and reproducible processing of workpieces. Other embodiments relate to a zoom lens having a quickly-variable focal length. Still other embodiments relate to various features of a laser-based multi-axis machine tool that can facilitate efficient delivery of laser energy to a scan head, that can address thermomechanical issues that may arise during workpiece processing, etc. Another embodiment relates to techniques for minimizing or preventing undesired accumulation of particulate matter on workpiece surfaces during processing. A number of other embodiments and arrangements are also detailed. 提供基于镭射的工具机及用于控制该工具机的技术的各种实施例。一些实施例是关于用以促进对工件的均一且可再现处理的技术。其他实施例是关于具有可快速改变焦距的变焦透镜。其他实施例是关于基于镭射的多轴工具机的各种特征，该等特征可促进镭射能量至扫描头的有效递送、可解决在工件处理期间可能产生的热机问题，等。另一实施例是关于用于最小化或防止颗粒物质在处理期间在工件表面上的不合需要的聚积。亦详述数个其他实施例及布置。
