Controlled microcones formation on high refractory metals under multipulsed laser irradiation

The problem of controlled formation of single tip-shaped micro- and nanostructures under the action of series of laser pulses have been considered. The possibility of production of tip-shaped bumps with heights up to 50 micrometers on the surface of high refractory metals under the action of the order of 100 submillisecond pulses have been experimentally shown.
