摘要：
Emission of neutral N atoms and CN molecules has been studied in the plasma produced by focusing a 200 mJ Nd:YAG laser onto a graphite target in air. Emission of atomic lines appears at early times. The Stark broadening of these lines is strongly time dependent due to the evolution of electron density in the plasma. At later times the spectrum is dominated by the CN violet system B2SIGMA-X2SIGMA. In the range from 1 to 20 mus the population of B2SIGMA rovibrational levels can be described by a temperature of about 8500 K.
