Abstract
Pulsed laser ablation of a NbTe2 target was performed by an excimer la ser in helium atmosphere at different fluences, Ablation plume charact erization was realized by optical Time-of-Flight spectroscopy. Velocit ies and kinetic energies of the ablated particles were determined as a function of the fluence and of the background pressure. We observed a n increase of the velocity of Te-2 molecules when increasing the heliu m pressure, We show that this effect is due to three bodies associativ e reactions between monoatomic Te species and background gas particles .
