Analysis of the emission bands of the CN molecules in the plasma generated from a graphite target irradiated with 1.06 μm
radiation pulses from a Q-switched Nd:YAG laser has been done. Depending on the position of the sampled volume of the plasma
plume, the intensity distribution in the emission spectra is found to change drastically. The vibrational temperature and
population distribution in the different vibrational levels have been studied as function of distance from the target for
different time delays with respect to the incidence of the laser pulse. The translational temperature calculated from time
of flight is found to be higher than the observed vibrational temperature for CN molecules and the reason for this is explained. 相似文献
