We demonstrate the formation of micro/nanoparticles and nanogratings on the zinc surface induced by a 150 fs, 775 nm laser. The nanoprotrusions or nanocavities of different sizes were fabricated by different laser pulses and laser fluences. A smaller nanoprotrusion or nanocavity can be produced by a smaller number of laser pulses and lower laser fluences. Also we report the formation of nanogratings and micro/nanoparticles when the laser beam scans the zinc surface. We observe a composite structure with nanogratings and microparticles on the zinc surface when the laser fluence is 0.3 J/cm. This phenomenon proves that the process of transformation from microparticles to nanogratings is a dynamic processing. Therefore, the use of femtosecond-laser ablation of zinc surfaces may be considered as an efficient technology to obtain various micro/nanostructures. [ABSTRACT FROM AUTHOR]
