The histogram (a) showing the distribution of the particle diameters in a colloidal system realized by laser irradiation of the monolithic target. The laser power used was either 50 W (red bars) or 90 W (green bars), the scanning speed was 100 μm/s in average. The scheme of CW-laser ablation process of a silicon target is shown in the inset.
