Application of laser matter interaction for generation of small-sized materials

Syntheses of nano particles have drawn considerable interest in the recent past because of their ability to offer superior properties to those of bulk materials. Reduction in the size of the materials can be performed with great precision via laser-matter interaction. We focus here on following two promising schemes: (a) selective ablation of thin films via high power laser interferometry and (b) manipulation of atomic trajectories via dipole force, to generate the small-sized materials in the form of ordered arrays of required configuration. Some of our preliminary investigations on both techniques are also presented
