Ultrafast laser microwelding for quantum technology

Etienne Pelletier, Dimitris Karnakis

Ultrafast laser micro-welding (ULMW) has emerged in recent years as a powerful technology for precise bonding of dissimilar materials. Moreover, because it does not rely on interlayers, ULMW avoids introducing unwanted contaminants, unlike other bonding solutions (e.g. de-gassing from adhesive bonding). In …

Smart laser microhole drilling: data-driven compensation and predictive process optimisation

Toby Barnard, Dimitris Karnakis

Laser microhole drilling often relies on empirical process optimisation methods due to beam imperfections, complex process parameters, and limited metrology. We present a structured, data-driven approach to improve process control and repeatability. Three case studies are discussed: (i) dynamic laser power modulation …

Measuring the principle Hugoniot of low-density silica aerogel foam at pressures up to 160 GPa

J. J. Lee, Peter Norreys, Robert Paddock, Matthew Oliver et autres

Low-density foams are of significant interest in inertial confinement fusion (ICF), with potential applications as fuel carriers, ablation layers, or as a hohlraum filling material. Despite their potential, the shock response of these materials remains poorly characterized, limiting the accuracy of hydrodynamic …

Unlocking vacuum entanglement

Andrew Steane, Haru Ishizaka

The structure of entanglement in the ground state of the harmonic chain is studied. A class of two-mode squeezed states, useful for this purpose, is identified. The entanglement of the local modes at the ends of the chain, after tracing out the …

Efficiency-optimized relativistic plasma harmonics for extreme fields

Robin J. L. Timmis, C. R. J. Fitzpatrick, Jonathan P. Kennedy, Holly M. Huddleston et autres

Abstract Bright harmonic radiation from relativistically oscillating laser plasmas offers a direct route for generating extreme electromagnetic fields. Theory predicts that under optimized conditions, the plasma medium can support strong spatiotemporal compression of laser energy in a coherent harmonic focus (CHF), delivering …
