The experimental set up used for the spectroscopic characterization of the Al pulsed laser ablation plasma is presented in the diagram below.

For excitation was used the second harmonic (Lambda=0.532 um, 180 mJ energy), of a Q-switched Nd:YAG laser (Lambda=1,064 um, 360 mJ energy), 4.5 pulse duration, 0.1-10 Hz repetition frequency.

The UV, visible and IR spectra of the Al pulsed laser ablation plasma was registered using an Acton Research spectrometer.
