Paper Abstract
It was performed a Time of Flight (TOF) study for the plume produced by laser ablation of cooper by 355 nm, 23 ns
duration laser pulses, in vacuum. The plume sensor was made of a piezoelectric PVDF film associated with a pair of
electrodes. By varying the electrodes polarization we evaluated the fraction of neutral atoms, which ranged from 8 to
30 % of the plume. By adjusting a TOF function to the PVDF electric signal we obtained the center of mass velocity and
the translational temperature. It was observed that product vCM × Tz remains constant with the electrodes potential and
that the accelerating potential to which the plume is submitted has practical limits.
