Nano-size silver colloids were prepared by using laser ablation in pure water. To modify shape of the nanoparticles, additional laser irradiation onto the colloidal particles was carried out. Size of particles was reduced due to laser-induced fragmentation. In addition, it was found that non-spherical nano-structures such as wires and sheets of silver were produced due to laser-induced fusion of particles. These findings suggest that shape of colloidal particles can be controlled by using laser ablation in liquids.
