In plasma emission spectra produced by pulsed laser ablation of Si target in air, under the assumption of local thermodynamic equilibrium (LTE), the electron temperature and the electron number density are calculated, respectively. It seems that LTE is valid in early stage of the laser induced plasma evolution.
