我们最近的研究表明，双脉冲激光诱导击穿光谱(DP-LIBS)在在线测量HL-2A装置清洗过程中第一反射镜上超薄共沉积层的激光烧蚀过程中具有很大的潜力。等离子体发射的光谱研究可以用来确定烧蚀材料的元素组成。在0.76J/μ的多次脉冲作用下，共沉积层(约0.8ncm2)被完全去除，但清洗激光脉冲引发的等离子体太弱，不能产生LIBS信号。使用DP-Libs可以观察到信号发射的显著增强。实时监测和准确识别界面边界可以提供有关清洗后镜面的重要信息，以避免清洗不足。这可以帮助我们开发更有效的聚变装置激光清洗过程的自动控制。
Our recent investigations have indicated that dual-pulse laser-induced breakdown spectroscopy (DP-LIBS) has great potential in the online measurement of the laser ablation process of the ultrathin co-deposition layer on the first mirrors of HL-2A tokamak during the cleaning. The spectroscopic study of the plasma emission can be used to determine the elemental composition of the ablated materials. The co-deposition layer (approximately 0.8 μm) was completely removed after multiple pulses at 0.76 J/cm2, but the plasma initiated by the cleaning laser pulse was too weak to produce LIBS signals. Notable enhancement of the signal emission was observed using DP-LIBS. The real-time monitoring and accurate identification the interface boundary can provide important information regarding the cleaned mirror surface in order to avoid under-cleaning. This could help us to develop more effective automatic control of the laser cleaning processes for fusion devices.
