DETERMINE EMISSIONS PLASMA IRON BY LASER-INDUCED BREAKDOWN SPECTROSCOPY IN ATMOSPHERIC ENVIRONMENT

Abstract

The plasma spectroscopy analysis for Iron induced plasma was carried out using a Q-switched Nd: YAG pulsed laser system. The Laser wavelength was (1064) nm, Emission spectra were obtained using different energies in the range (600-900) mJ. Electron temperatures are evaluated at different laser peak powers from Boltzmann (-1/KBT) and Suha equation, also, the electron densities are deduced using stark broadening. A limited number of suitable Fe lines are detected and the plasma parameters are discussed. The Electron temperatures of (Fe) are measured and were found to be in the range of (1.8–1.88) eV. It is observed in the case of iron the electron temperature is proportional with laser energy and the highest peak in (Fe) arrive at (55396.52).
