Abstract
Optical emission studies of molecules in plasma obtained by Nd:YAG laser ablation of graphite in a helium atmosphere are reported for irradiances in the range (1 - . The characteristics of the spectral emission intensity from the (Swan band) species have been investigated as functions of the distance from the target, ambient pressure and laser irradiance. Estimates of vibrational temperatures of species under various irradiance conditions are made. Results of measurements performed under different ambient helium gas pressures are also discussed.
