激光烧蚀高纯Zn形成的微米金属球体对后续脉冲激光的耦合增强效应*OA北大核心CSCDCSTPCD
Effect of laser-induced zinc micro-spheres on enhanced absorption of subsequent pulse laser*
脉冲激光束在低真空(约2 Pa)环境下聚焦到高纯Zn靶表面，烧蚀区域不仅有中心深孔的宏观损伤，而且还发现大量微米量级的类似足球形状的金属Zn球体结构附着生长在孔洞内侧表面.实验过程中采用等离子体光谱诊断技术研究宏观和微观损伤对后续脉冲激光的影响程度.与聚焦于金属Zn平滑表面相比，宏观损伤可以使后续激光诱导的Zn原子334.5 nm谱线强度提高10.3%，在此基础上大量Zn微米球体附着在内表面可以使谱线强度再提高34.3%.因此，推断这些金属Z…查看全部>>
Numerous football-shaped Zinc micro-spheres on inner surface of the crater are produced by pulsed laser ablation of Zn metals in vacuum condition (∼2 Pa). Pulsed laser induced plasma emission spectrum is measured to reveal the effects of macro-and micro-structures on subsequent pulse laser ablation. The intensity of spectral line at 334.5 nm originating from Zn atoms by subsequent laser ablation of the ablated spot is 10.3% higher than that created over a …查看全部>>
