Targets with microstructured front surfaces have shown great potential in improving high-intensity laser–matter interaction. We present cone-shaped microstructures made out of silicon and titanium created by ultrashort laser pulse processing with different characteristics. In addition, we illustrate a process chain based on moulding to recreate the laser-processed samples out of polydimethylsiloxane, polystyrol and copper. With all described methods, samples of large sizes can be manufactured, therefore allowing time-efficient, cost-reduced and reliable ways to fabricate large quantities of identical targets.

具有来自各种材料的锥形微结构的目标，用于增强高强度激光与物质的相互作用

具有微结构前表面的目标在改善高强度激光与物质的相互作用方面显示出巨大的潜力。我们展示了由具有不同特性的超短激光脉冲处理产生的由硅和钛制成的锥形微结构。此外，我们还展示了基于成型的工艺链，以用聚二甲基硅氧烷、聚苯乙烯和铜重新制作激光加工样品。使用所有描述的方法，都可以制造大尺寸的样品，因此可以以高效、低成本和可靠的方式制造大量相同的目标。
