Abstract

Through optical emission spectroscopy, zinc (Zn) plasma produced on the basis of a laser can be investigated in the proposed study. Zinc plasma spectral emissions were studied as a function of laser energy (200, 300, 400, and 500) mJ. Record plasma emission with a 100 ns integration time. The spectral lines of zinc were determined, and the electron temperature (����) and electron density (����) were studied using Boltzmann diagrams. It is noted from the results that as the laser energies increase, the values of ���� and ���� rise as well, as the values range from (1.075−1.467) eV for electron temperature, while the electron density values range (2.939×10^18−3.535×10^18)����^−3. Also, in this paper, other parameters investigated included Debye length (_D), FWHM, and plasma frequency (fp).
