Glass tube cutting with aberration-corrected non-diffracting ultrashort laser pulses

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