摘要
High transmissivity of transparent materials in a wide range of wavelength increases its difficulty of machining using lasers. Laser beam passes through the material, producing no thermal effect on the transparent sheet. Conversely, the technique Laser-Induced Plasma Assisted Ablation (LIPAA) is capable of addressing the challenge of machining transparent materials with the aid of laser-induced plasma. This paper reports a three-dimensional nonlinear transient modeling and simulation of the LIPAA process for microchannel fabrication on transparent materials. The merit of the approach lies in simulating simultaneous ablation of both transparent polycarbonate and aluminium metal target during the process. The effect of plasma energy besides input laser irradiation has also been considered to have a realistic approach to the process and consequently, ablation on rear side of polycarbonate is obtained. The developed model has the potential of estimating spatial-temperature distribution along the traverse direction and direction perpendicular to it. The spatial distribution lent a hand in predicting the width and depth of the microchannel. A good correlation between the simulated and the experimental results was achieved on validation. Temporal-temperature distribution for pulse-on and pulse-off time was also explored. It is witnessed that the heating rate during pulse-on time is more than the cooling rate during pulse-off time. Likewise, it is observed that the temperature generated on aluminium is more than on polycarbonate. Substantially, the model can be employed to demonstrate LIPAA for microchannel fabrication on transparent materials irrespective of its transitivity.
