Abstract

Recently we developed a new method of spherical submicron particle production by pulsed laser irradiation of primary small irregular nanoparticles suspended in liquid. For the first time we demonstrated that the nanoparticles can not only reduce their sizes under the pulse laser irradiation, but can grow essentially. To control the particle formation process, the mechanism of particle interaction with laser pulse has to be understood. Particle heating-melting-evaporation model was successfully applied to clarify this mechanism.
