Kinetic approach for the particle size distribution function under high-speed laser cooling from the melt is discussed. The Fokker-Planck equation was decided exactly for broadly realized in practice lamellar (dendrite) nucleation in the cases of laser surface coating, micro cladding or amorphization. There were determined expressions for an average size of the crystallizing nucleus, as well as a relative fraction of the solid phase volume. Submicron particle distribution by sizes, average radius and density of new growing phase are evaluated numerically depending of regimes of a laser influence. Influence of morphology, chemical state (catalytic properties) and deformations on the kinetic of phase transformation are discussed. It is shown, that within the framework of considered kinetic approach it is possible to describe different regimes of laser assisted surface modification including nano fabrication. A new criterion of amorphous state after high-speed laser cooling is proposed.
