Abstract
This article presents the use of piezoelectric PVDF films as a sensor for the vapor stream in laser ablation experiments. The analysis of the PVDF electric signal gives the translational temperature and the vapor drift velocity of the ablated plume. A PVDF sensor was used in a tungsten ablation experiment, using HyBrID copper laser, and it was obtained a translational temperature of 9×104 K and a drift velocity of 4×105 cm/s.
