“…Laser ablation powered by inexpensive, robust, high-power nanosecond (ns) lasers appears to be a chemically clean, environmentally “green” key enabling process for industrial manufacturing of functional nanomaterials, for example nanoparticles (NPs), in liquids for diverse promising applications: Hydrogen generation, storage, and catalysis [ 1 , 2 , 3 ]; Wound healing, anti-cancer, anti-bacterial, and anti-fouling activity, and biosensing [ 4 , 5 , 6 , 7 , 8 , 9 ] in biomedicine; Additive nano-assembling of novel materials [ 10 , 11 , 12 , 13 , 14 ]; Non-linear nanophotonics [ 15 , 16 , 17 ]; NP-mediated/enhanced nuclear reactions [ 18 ] and many others (for the broad reviews, see, e.g., [ 19 , 20 , 21 , 22 , 23 ]). …”

Transient NP formation inside the laser-driven vapor bubbles (the intermediate stage two) was envisioned just recently via spatially- and temporally-resolved sophisticated X-ray transmission studies in liquids [ 26 ].…”

A comprehensive picture of the nanosecond-laser generation of colloidal nanoparticles in liquids is nowadays the demand of their high-throughput industrial fabrication for diverse perspective biomedical, material science, and optoelectronic applications. In this study, using silicon as an example, we present a self-consistent experimental visualization and theoretical description of key transient stages during nanosecond-laser generation of colloidal nanoparticles in liquids: plasma-mediated injection of ablated mass into the liquid and driving the vapor bubble, finalized by the colloid appearance in the liquid. The explored fundamental transient stages envision the basic temporal and spatial scales, as well as laser parameter windows, for the demanded high-throughput nanosecond-laser generation of colloidal nanoparticles in liquids.
