Characteristics of CaFe Plasma Parameters by Laser-Induced Breakdown Spectroscopy Technique

Abstract

In this work, the effect of laser energy on the properties of a CaFe plasma generated by a Q-switched Nd: YAG laser
at the fundamental wavelength was studied using spectroscopy. The Boltzmann plot and Stark broadening method
were used to measure the main plasma parameters (electron temperature and electron density). The electron
temperature ranged (1.295 -1.929) eV, the electron density ranged (2.25 - 3) × 1018
