The separation of complex inner and outer contours of glass articles with curved surfaces using ultrashort pulsed lasers is reported. Single-pass, full-thickness modifications along the entire substrate are achieved using a processing optics that allows for beam shaping of non-diffracting beams and, additionally, for aberration compensation of phase distortions occurring at the curved interface. The glass articles finally separated by thermal stress or via selective etching meet the demands of the medical industry in terms of micro-debris, surface quality, and processing speed.

使用像差校正的非衍射超短激光脉冲切割玻璃管

报道了使用超短脉冲激光分离具有曲面的玻璃制品的复杂内外轮廓。使用加工光学器件实现沿整个基板的单程、全厚度修改，该加工光学器件允许对非衍射光束进行光束整形，此外，还可对弯曲界面处发生的相位失真进行像差补偿。最终通过热应力或选择性蚀刻分离的玻璃制品在微碎屑、表面质量和处理速度方面满足医疗行业的要求。
