Abstract

In this work thin films were produced by Laser Induced Forward Transfer (LIFT) and characterized. Picoseconds Nd YAG laser was used to irradiate pure samples of Fe and the plasma plume was deposited as thin films on two different types of substrate; the first one from copper and the second one from agate (SiO2). The thin films were characterized using scanning electron microscope (SEM) and Energy Dispersive Analysis of X-rays (EDAX) in addition to scratch and scotch-tape for adhesion test. The effects of laser power density, the target thickness and the type of substrate on the homogeneity and adhesion of the films were investigated. The best conditions were: 2 X1013 W/cm2 laser power density, 2 m target thickness and agate substrate. Thin films with high quality were deduced using these conditions.
