我们报告使用157 nm F2激光辐射烧蚀聚碳酸酯和聚烯丙基二甘醇碳酸酯（CR39）上形成的圆锥形微观结构。它们的特点是具有光滑，直的壁，对于CR39，尖锐的尖端，以及它们底部周围的干涉和衍射条纹。蚀刻速率建模的非平面表面和衍射调制的注量是用来探索如何锥可能演变，和估计是由微锥上的热负荷。
We report on conical microstructures formed on polycarbonate and polyallyl di-glycol carbonate (CR39) ablated using 157-nm F2 laser radiation. These are distinguished by having smooth, straight walls and, for CR39, sharp tips, together with interference and diffraction fringes around their base. Etch-rate modelling of a non-planar surface and diffraction-modulated fluence is used to explore how cones may evolve, and an estimate is made of thermal loading on microcones.
