在铜上形成了飞秒激光诱导的人字形图案。这些新的周期结构是在S偏振的大入射角飞秒激光脉冲作用下产生的。形成倾斜的和轴对称的激光诱导的周期性表面结构沿消融通道的侧壁，结果是一系列类似人字形图案的V形结构。已经进行了注量图、入射角研究以及偏振研究，并提供了对这种新结构的清楚了解。
Femtosecond laser-induced herringbone patterns are formed on copper (Cu). These novel periodic structures are created following s-polarized, large incident angle, femtosecond laser pulses. Forming as slanted and axially symmetric laser-induced periodic surface structures along the side walls of ablated channels, the result is a series of v-shaped structures that resemble a herringbone pattern. Fluence mapping, incident angle studies, as well as polarization studies have been conducted and provide a clear understanding of this new structure.
