46th International Workshop on High Energy Density Physics with Intense Ion and Laser Beams

The continuous advancement of high‑power laser systems, including those driving inertial confinement fusion experiments, demands optical coatings with exceptionally high laser‑induced damage thresholds (LIDT) and precise control over optical and mechanical properties.

This work presents recent developments in the deposition of high‑LIDT coatings optimized for pulsed laser applications....

The strategy to achieve high gain in Inertial Confinement Fusion (ICF) necessitates flexible laser beamlines capable of delivering diverse temporal characteristics at the kJ energy level. While direct drive target compression demands broad-bandwidth nanosecond pulses, specific ignition schemes require short pulses to generate penetrating particles. Consequently, advanced spectral management is...

The interaction between ultra-short, high-power laser pulses and solid-density targets is frequently utilized to accelerate protons [1-3] and heavier ion species [4]. Since then, it has been shown that structuring the surface leads to enhanced absorption of the laser and enhanced conversion to secondary radiation. Ruhl and Korn [5] have proposed using nanowire arrays with average density near...
