提出了一种利用二维微球晶格聚焦激光制作纳米图形的方法。阵列以一种可控制的方式放置在样品表面附近，以亚微米精度找到焦平面。这项技术已被应用于Fe-Cr层的直接图案化，该层表现出激光诱导的磁性改变。所获得的数据表明图案化特征中出现了一些不规则性。为了理解：(1)观察到的不规则性的原因以及(2)如何获得小的图案特征，使用了散射光强度的Mie解。
An approach to nanoscale patterning using focused laser beams by two-dimensional lattices of microspheres is presented. The arrays were positioned in a controllable way near the sample surface with submicron accuracy to find the focal plane. This technique has been applied for direct patterning of Fe–Cr layers which exhibit laser-induced modifications in magnetic properties. The obtained data indicate the occurrence of some irregularities in the patterned features. To understand: (1) The reasons for the observed irregularities and (2) how small patterned features can be obtainable, the Mie solution for the intensity of scattered light has been used.
