Ultrafast Tracking of the Spallation Layer in Bulk Gold, Aluminum, and Steel
Nicolas Thomae, Julian Vollmann, Julian Freundel +3
Extreme manufacturing with ultrashort-pulse (USP) lasers at the physical limit of precision and efficiency requires understanding ablation dynamics on the picosecond-to-nanosecond…
Threefold Efficiency Enhancement and Narrowed Nanoparticle Size Distribution in Laser Ablation of Gold in Water by GHz-Burst Irradiation
Maximilian Spellauge, Ramon Auer, Vincent Taebling +3
Laser ablation in liquids enables the synthesis of surfactant-free nanoparticles but remains limited in productivity due to intrinsic constraints imposed by the liquid environment.…
Breakdown of spallation in multi-pulse ultrafast laser ablation
David Redka, Julian Vollmann, Nicolas Thomae +2
Ultrashort-pulse laser ablation of metals near damage threshold is governed by homogeneous spallation, in which tensile unloading releases a nanometre-thin liquid film whose optica…
Microparticle laser fragmentation in liquids: mechanisms, energetics, and efficiency quantified with single-pulse, single-particle precision
Maximilian Spellauge, Ramon Auer, Meike Tack +6
Microparticle laser fragmentation in liquids has emerged as a promising approach to generate nanoparticles with high efficiency. Despite its advantages, the underlying fragmentatio…
