The results from experimental and theoretical investigation of material pulsed laser treatment aimed at obtaining nano‐ and microstructured surface are presented. An experiment has been performed on the modification of indium surface using a solid‐state diode‐pumped laser. It has been shown that nano‐ and micro‐size structures are formed under laser melting and fast crystallization of the metal surface. The kinetics of the crystallization of metals under superfast cooling. The distribution function for crystalline nuclei dimensions is analytically found within the framework of the classical kinetic equation in case of superfast temperature changing. The average number of particles in the crystalline nuclei and relative volume of the crystalline phase are determined as functions of thermodynamic and laser treatment regime parameters. Good agreement is observed with experimental results for ultrashort laser pulses induced micro‐ and nanostructures production.
