Pulsed laser ablation in liquids: Impact of the bubble dynamics on particle formation
Abstract
Pulsed laser ablation in liquids (PLAL) is a multiscale process, involving multiple mutually interacting phenomena. In order to synthesize nanoparticles with well-defined properties it is important to understand the dynamics of the underlying structure evolution. We use visible-light stroboscopic imaging and X-ray radiography to investigate the dynamics occurring during PLAL of silver and gold on a macroscopic scale, whilst X-ray small angle scattering is utilized to deepen the understanding on particle genesis. By comparing our results with earlier reports we can elucidate the role of the cavitation bubble. We find that symmetry breaking at the liquid-solid interface is a critical factor for bubble motion and that the bubble motion acts on the particle distribution as confinement and retraction force to create secondary agglomerates.

A minimum ablation duration of 5 minutes is required to obtain a reliable gram-per-hour value while accounting for nanoparticle shielding, target depth variation, persistent microbubbles, and scanning and repetition rate effects.
“For this reason, the minimum ablation duration of 5 minutes is required to obtain a reliable gram per-hour value while also accounting for the effect of nanoparticle shielding, 76 target depth variation, persistent microbubbles, 84 and scanning and repetition rate effects.54”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
