In this paper the effect of external DC electric field on the ablation rate was studied. The sample is brass alloys (35% Zn - 65% copper), which is exposed to radiation from a Nd:YAG laser beam with  pulse duration of 10 ns and 10Hz repetition rate. Furthermore, in each case, the target was irradiated by laser beam with 1500 pulses for a total time of 2.5min. The radiation was carried out in two conditions, with and without the electric field perpendicular to the laser beam path. The craters formed on the target and the optical properties of the colloid solution containing nanoparticles were studied using optical microscopy and UV-Vis optical absorption spectrometry, respectively. The results show that the external electric field can significantly influence the ablation rate and consequently the concentration of nanoparticles in water.
Keywords: Brass alloy, ablation rate, nanosecond pulse laser, laser ablation, external electric field.
