An experimental investigation of the breakdown in Nitrogen at 1.5 atm under intense radiation from a Q-switched Nd: glass Laser (peak power 1 MW) is presented. Two main techniques were used: Spectroscopic methods gave information on the axial and radial growth of the emitted light intensities. The image converter streak technique and Schlieren photography were used to investigate the propagation of the shock waves. This paper includes the radial and temporal distribution of the plasmaparameters temperature and electron density in the focus region, but also in distances of 240 /μm from the focus. It was found that local thermal equilibrium is established within about 10-14 ns, but only in a small part of the spark
