Ultrafast laser microwelding for quantum technology
14 April 2026 • 10:05 - 10:20 CEST | Curie A (Niveau/Level 1)
Abstract
We will present recent advances in ultrafast laser micro-welding (ULMW), focusing on we use it to create hermetic seals for quantum technology, such as miniaturised ion traps for quantum networking. With our main target being welding silica-based crown glass to titanium grade 2, we produced robust hermetic samples, reaching helium leak rate below 10-10mbar∙l/s. This important first step opens the door to a new and efficient way to produce miniaturised quantum systems.
