论文摘要
我们介绍了使用高平均功率激光器的新型模块化气体目标的设计和实施。为了确保在这个高热负荷环境中的热稳定性,我们实施了适当的液体冷却系统。该系统可用于多细胞配置,以控制单元格的长度和孔径大小。通过热和流量模拟进行热特性,真空兼容性和生成培养基特性,优化了细胞设计。最后,通过使用100 kHz的高平均功率HR-1激光系统在极端光基础设施attosecond tosecond Light Pulse(ELI ALPS)设施进行高阶谐波生成测量来对细胞系统进行实验验证。在台式实验室系统和以用户为导向的设施(例如ELI ALPS)中,这种强大的,多功能和可堆叠的气电池排列可以很容易地适应不同的实验几何形状。
We present the design and implementation of a new, modular gas target suitable for high-order harmonic generation using high average power lasers. To ensure thermal stability in this high heat load environment, we implement an appropriate liquid cooling system. The system can be used in multiple-cell configurations allowing to control the cell length and aperture size. The cell design was optimized with heat and flow simulations for thermal characteristics, vacuum compatibility and generation medium properties. Finally, the cell system was experimentally validated by conducting high-order harmonic generation measurements using the 100 kHz high average power HR-1 laser system at the Extreme Light Infrastructure Attosecond Light Pulse Source (ELI ALPS) facility. Such a robust, versatile and stackable gas cell arrangement can easily be adapted to different experimental geometries in both table-top laboratory systems and user-oriented facilities, such as ELI ALPS.
