    Abstract:

    There are a number of commercially available lasers with different emission parameters. Among these, wavelength, continuous or pulse emission, pulse repetition rate and nominal power are essential. The laser emission can further be modified by the optical systems employed to modulate the output beam.
    The above laser emission parameters enable controlled irradiation of solids to induce significant chemical and physical modifications of their surfaces in any type of environment and with ease of scalability to large areas.
    Several distinct types of interactions may be described for laser irradiation of solids, with underlying photothermal, photophysical and photochemical mechanisms. The most commonly applied in industry are based on photothermal transformations, where melting is induced on solid surfaces for welding and conventional cutting operations. Appropriate beam steering enables focusing geometries which allow directional solidification of solids from their melt in circular and planar fashion. In contrast, short pulse laser irradiation of solids may induce ablation phenomena, whereby material is selectively removed from the irradiated area, generating new surface properties.
    The above processes will be examined in this talk, using examples derived from the preparation of textured and nanostructured functional solid surfaces.
