    Optical properties of femtosecond laser-treated diamond

    A laser-induced periodic surface structure (LIPSS) has been fabricated on polycrystalline diamond by an ultrashort Ti:Sapphire pulsed laser source (λ = 800 nm, P = 3 mJ, 100 fs) in a high vacuum chamber (<10−7 mb...

    Raman investigation of femtosecond laser-induced graphitic columns in single-crystal diamond

    We report on the fabrication of graphitic columns induced in single-crystal diamond plates using 100 fs laser pulses at 800 nm wavelength. Different values of laser fluence (0.6–1.2 J/cm2) and graphitization spee...

    AlN thin films prepared by ArF plasma assisted PLD. Role of process conditions on electronic and chemical–morphological properties

    Aluminium nitride thin films were deposited on n-Si <100> substrates by RF plasma activated reactive pulsed laser deposition (PLD). An ArF excimer pulsed laser, 10 Hz and 2.5 J/cm2 energy fluence, has been used t...

    Critical role of laser wavelength on carbon films grown by PLD of graphite

    The structure of thin films deposited by pulsed laser ablation (PLD) is strongly dependent on experimental conditions, like laser wavelength and fluence, substrate temperature and pressure. Depending on these ...
