铜是最重要的金属之一，暴露于红外辐射。使用Nd：YAG激光器（1064 nm，1.1 MW，12 ns）在真空度为100 - 10 - 6 μ m的条件下对精细抛光和退火的样品（4 N，1×1×0.3 cm 3）进行100次激光照射。靶上的激光焦斑尺寸和功率密度分别为12 μm和3×1012 Wm−2。通过扫描电子显微镜和X射线衍射图（XRD）分析，分别进行表面和结构的研究。激光烧蚀导致沸腾、飞溅、流体动力溅射和剥离沿着其它相关现象。暴露样品的XRD图案表明衍射强度和晶粒尺寸的变化。对于被照射的靶，原子平面保持不受干扰。收集的信息对于研究辐射-金属相互作用中发现的复杂性是有用的。
Copper, one of the most significant metals, is exposed to IR radiation. A Nd:YAG laser (1064 nm, 1.1 MW, 12 ns) has been used to irradiate fine polished and annealed samples (4 N, 1×1×0.3 cm3) with 100 laser shots under a vacuum of ∼10−6 torr. The laser focal spot size and power density on the target were 12 μm and 3×1012 Wm−2 respectively. The surface and structural studies were performed by analyzing scanning electron micrographs and X-ray diffractograms (XRDs), respectively. Laser ablation results in boiling, splashing, hydrodynamical sputtering and exfoliation along with other relevant phenomena. The XRD patterns of the exposed sample indicate a change in diffraction intensity and grain sizes. The atomic planes remain undisturbed for the irradiated target. The information collected is useful for investigating the complexities found in radiation–metal interactions.
