Usually, laser drilling with standard single femtosecond pulses results in tapered holes of strongly limited length and rough inner surface.<\/p>\n<p>This new laser-matter interaction regime makes it possible to directly drill holes of high aspect ratio in one single step without any chemical etching. The choice of the laser-burst parameters was revealed to be very important in order to achieve an outstanding micromachining quality of the machined structures. The femtosecond laser GHz-burst mode could pave the way for new applications such as microelectronics where silicon interposers are likely to be replaced by glass interposers.\n                                                                                                                            <\/p>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Pierre Balage et al, Crack-free high-aspect ratio holes in glasses by top\u2013down percussion drilling with infrared femtosecond laser GHz-bursts, <i>International Journal of Extreme Manufacturing<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1088\/2631-7990\/acaa14\">DOI: 10.1088\/2631-7990\/acaa14<\/a><\/p><\/div>\n<p>                                                Provided by<br \/>\n                                                                                                    International Journal of Extreme Manufacturing<\/p>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                <strong>Citation<\/strong>:<br \/>\n                                                Exploring a new glass micro-drilling method using a femtosecond laser in GHz-burst mode (2022, December 29)<br \/>\n                                                retrieved 2 January 2023<br \/>\n                                                from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-12-exploring-glass-micro-drilling-method-femtosecond.html<\/p>\n<p>                                            This document is subject to copyright.
