- Analysis of Time-Resolved Laser Plasma Ablation using an Imaging Spectra Technique H. Luna J. Dardis D. Doria J.T. Costello Física, Astronomía y Matemáticas Time Spectroscopy Plasma density resolved imaging Plasma temperature Pulsed laser deposition (PLD) is extensively employed for the growth of thin films. The laser-material interactioninvolves complex processes of heating, melting, vaporization, ejection of atoms, ions and molecules,shock waves, plasma initiation, expansion and deposition onto a substrate. The understanding of the spatialand temporal distribution of a plasma parameters in a laser-produced plasma is important to the control of thinfilm growth process. In this work we have studied the dynamics of laser ablated graphitic carbon plasma expandinginto vacuum using a spectroscopic imaging suitable as an in situ & automated diagnostic samplingtechnique for PLD. Time-resolved spectra, that were also spatially resolved in one dimension along the axisof plasma expansion, were obtained using a time-gated intensified charge-coupled device (ICCD) coupled toa stigmatic Czerny-Turner spectrograph. Plasma parameters such as electron density, temperature and plumevelocity expansion were extracted directly from the analysis of the C II (2s23d-2s24f) transition 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437818 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4 Vol.37
