When pulsed laser ablation is performed using a pipe and gas flow in an ambient gas, spherical nanoparticles with diameters ranging from tens to hundreds of nm are deposited on the substrate. When the position of the pipe was moved away from the irradiation point, aggregates of nanoparticles, "Web-like nanoparticle aggregates," were also deposited. This result suggests that the flow induced by the shock wave causes the nanoparticles to move outward and form an aggregate structure.
