“…In addition to laser properties such as wavelength, pulse energy, and pulse width; the nature of the target material and the surrounding environment; as well as the measuring equipment, are factors that can impact LIBS [6][7] . As a result of these factors, the repeatability of the LIBS signal is low, which is one of the key challenges that hamper the deployment of LIBS technology 8,9 .…”

Optical Emission Spectrometry technique (OES) is used to analyze the plasma generated from a (Ni) target illuminated with a Q- Switched (Nd:YAG) laser at various energies in the air. Boltzmann-Plot and Stark broadening methods were used to calculate the plasma parameters including electron density (ne), electron temperature (Te), plasma frequency (fp), and Debye length (λD). It is shown that the values of (ne), (Te), (λD) and (fp) increase with increasing laser energy with the calculated electron temperature values ranging between 0.934 - 1.479 eV.
