Abstract

Plasmas were produced by laser-induced breakdo wn in nitrogen, oxygen and air at 1 atm using the 1.06 μm beam from an YAG la ser .The spectra of these plasmas in the range of 400-800 nm were obtained. The preliminary result shows that all the spectra consist of a strong continuous ba ckground and some line structures. With delay sampling, the spectra vary remarka bly. By sampling at the different position of the plasmas, the spectra change in a special way. The quantitative analysis is in progress.
