In this paper we studied the main conditions for the Plasmas generation air, copper and aluminum, using a laser Nd: YAG pulsed with wavelength 1064 nm with a pulse of 500 mJ Energy and 9 ns duration at a repetition rate of 10 Hz. Through spectroscopy, we have analyzed Optical Emission lines Spectral emission, which were obtained by varying the Atmospheric pressure. Emissivity to High pressure is greater because of the confinement of the plasma and Increasing collisions between different species, in the case Plasma in the air we compared the data obtained from each Wavelength due to each transition and electronic state of Ionization with wavelengths characteristic of each Element reported by the database of the NIST (National Institute of Standards and Technology).
