Abstract: (859 Views)
In the present work, the effect of external DC electric field on the ablation rate during nanosecond pulsed laser ablation of Tin in ethanol was studied. In this study, the target (Tin 99.9%), was irradiated by 500 pulses of Nd:YAG laser beam with pulse duration of 10 ns and 10Hz repetition rate. The irradiation was performed in the presence and absence of external DC electric field. The effect of electric field strength on the material removal rate was investigated for the condition in which the electric field was perpendicular to the laser beam path. The craters formed on the target surface were characterized by using optical microscopy and image processing technique. The results indicated that pulsed laser ablation in the presence of an electric field significantly leads to higher material removal rate.
