[Laser Institute of America ICALEO? 2016: 35th International Congress on Applications of Lasers & Electro-Optics - San Diego, California, USA (October 16–20, 2016)] International Congress on Applications of Lasers & Electro-Optics - Ultrafast laser trepanning process and modeling

摘要： We present an engineering model of ultrafast laser ablation with normal or non-normal (oblique) laser beams. It can be applied to trepanning drilling but also to zero-taper cutting. Specific experiments on line ablation are presented to understand how oblique beams can control the walls conicity. Industrial strategies for processing with high throughput and high quality are considered.
