  • Optodynamic measurements of Q-switched Nd:YAG laser drilling of laminated aluminium
    Strgar, Simon ; Diaci, Janez ; Možina, Janez
    Pulsed laser drilling of laminated aluminium sample with a Q-switched Nd:YAG laser was studied. A strong correlation between the depth of the laser-drilled hole and an optodynamic response was found ... and examined with the aim to explore the possibility of on-line monitoring of the hole depth growth. The optodynamic responses were acquired by means of a single laser beam deflection probe which detected shock waves generated in surrounding air during the drilling process. Detected signals were processed and analyzed to extract the optodynamic characteristics of the drilling process. The characteristics were correlated with geometric properties of the holes. Experiments were performed to examine how the deflection signal characteristics, hole depth, and material removal rate change with the number of consecutive laser pulses.
