The article reports on the manufacturing of high-performance laser marking systems. Most of metal laser marking applications are done with Q-switched Nd:YAG lasers, which provides a short pulse with high peak power. However, marking of synthetic materials and paint layers borrows some techniques from metal engraving and annealing. On the other hand, diode-pumped Nd:YAG lasers are the choice for demanding applications such as engraving and high quality annealing.

    High Schottky barrier height of [lowercase_phi_synonym]b=0.77 eV for Al/n-Si was obtained by the nozzle jet beam deposition method in a conventional vacuum condition without post-annealing. Previously, this high barrier height was only observable in the vacuum cleaved or sputter-etched samples...
