It is shown that in the course of laser processing with radiation flux density ~106 W/cm–2 in the external electric field with different polarity varying from 0 to 106 V/m-1 the change in the evolution features of the plasma torch at the surface of some metals (Cu, Al, Pb) at early stages is quantitative rather than qualitative. At the same time the characteristic size of the target material droplets carried out from the irradiated zone, becomes by several times smaller as the amplitude of the external electric field strength grows, independently of its polarity. |
