超短脉冲激光烧蚀材料是一种具有广泛应用前景的材料加工技术。本文介绍了我们对人工晶状体用医用高分子材料的切割研究。为了获得最佳结果，确定了皮秒脉冲对透镜材料的单次和多次照射的烧蚀特性和烧蚀阈值。结果用于孵育效应的定量。此外，切削实验进行，从而可以观察到不同的损伤类型。一个过程窗口的开发包含的区域的相应类型的损害和支持的理论考虑。
Material processing by ultra-short pulsed laser ablation is an attractive approach for various applications. In this paper we present our studies on cutting of medical polymers used for intraocular lenses (IOL). To achieve best results the ablation characteristics and the ablation thresholds are identified for single and multiple irradiation of the lens material by picosecond pulses. The results are used for quantification of the incubation effect. Furthermore, cutting experiments are carried out and thereby different damage types can be observed. A process window is developed containing the regions of the respective types of damages and backed up by theoretical considerations.
