摘要

摘要综述了利用超短紫外激光脉冲在各种材料上制备周期性表面图案的方法。使用两个或多个相干光束的激光干涉烧蚀导致确定性的、严格的周期性图案。干涉光束的产生是通过衍射光学元件如光栅、光栅系统或计算机生成的全息图来实现的。衍射光束的复合通过光学成像或衍射光束管理来执行。超短紫外线脉冲特别适合在金属和半导体上产生微米到亚微米大小的确定周期性图案。

Laser interference ablation by ultrashort UV laser pulses via diffractive beam management

Abstract The fabrication of periodic surface patterns on various materials by ultrashort ultraviolet (UV) laser pulses is reviewed. Laser interference ablation using two or more coherent beams leads to deterministic, strictly periodic patterns. The generation of the interfering beams is accomplished by diffractive optical elements like gratings, grating systems or computer-generated holograms. The recombination of the diffracted beams is performed by optical imaging or diffractive beam management. Ultrashort UV pulses are especially suited for generating micron- to submicron-sized deterministic periodic patterns on metals and semiconductors.
