Mechanisms of Laser Ablation in Liquids and Their Impact on the Efficiency of Nanoparticle Generation

Laser &Photonics Reviews, EarlyView.
Laser ablation in liquid enables nanoparticle synthesis from diverse materials but remains less energy‐efficient than ablation in air. This study quantifies the absorption‐corrected ablation efficiency and experimentally confirms redeposition as the key loss mechanism using pump‐probe microscopy.
