SUMMARY Laser irradiation for colloidal gold nanoparticles stabilized by Na 2 CO 3 was carried out to prepare submicron‐sized spherical particles of gold. The source gold nanoparticles stabilized by Na 2 CO 3 (CO 3 2− ) were prepared using laser ablation in an aqueous solutions containing Na 2 CO 3 and then nonfocused laser irradiation for the source nanoparticles was carried out to induce the agglomeration and fusion of the nanoparticles. Similarly to the case using the source nanoparticles stabilized by citrate, submicron particles were obtained. It was found that the formation process and size of the submicron particles strongly depend on the stabilizing reagents.
