Passat picosecond lasers drill routinely through milimiter(s)-thick materials

A micro-hole with aspect ratio of almost 200! Yes, that is an opening with 10 microns (or less) minimum diameter, going all the way through a 1.8-mm-thick heterogeneous “sandwich” of metal and dielectric materials. This is possible with Passat’s picosecond lasers and mind you, not any special, high-energy device, but a standard run-of-the-mill product. In [...][...]
