| Abstract | Abstract.We present an optodynamical method for the real-time determination of the depth of laser-drilled holes. The method consists of the detection of shock waves generated during the interaction of the laser beam with the irradiated material using a piezoelectric transducer (PZT), and measurement of the shock waves propagation time through the sample using the PZT signal. The experimental observations reveal that the propagation time has an almost exponential decay with the number of pulses and is strongly dependent on the laser radiation wavelength. The quantity of ablated substrate material per laser pulse is a nonlinear function of the number of consecutive laser pulses incident on the same spot at the irradiated sample surface. |
