Abstract
The plume generated by the Pulsed Laser Deposition (PLD) has been analyzed with an Optical Multichannel Analyser (OMA). A Nd-YAG laser source operating at 532 nm has been used to grow BiSrCaCuO (BSCCO) superconducting thin films from a 2:2:2:3 Pb-doped BSCCO target. The analysis has also been carried out while growing the BSCCO films on MgO substrates. The OMA spectra report the presence of excited species, neutrals and ionized, within the plume produced by ablation. The spectra recorded at different distancies from the target and at different oxygen pressures give indications on the nature and the velocities of the species ejected from the target.
