Measurement the Parameters of Cadmium Oxide Plasma Induced by Laser

Abstract :

In the present work, we studied the optical emission spectra of cadmium oxide (CdO) plasma produced by the
fundamental (1064 nm) wavelength of an Nd: YAG laser at vacuum in the range 200-800 nm, The plasma parameters such as electron temperature and electron number density have been extracted using Boltzmann plot method and Stark broadened line profile, respectively. The lines at 347.354 nm, 361.757 nm, 468.467 nm, 480.469, 509.274 nm and 644.79 nm are taken for the temperature calculations and also election of OI line 777.5388 nm to Calculate electron density. The change in electron temperature and the number of densities was studied as a function of the laser energies. In addition, the plasma frequency, the length of Debye and the Debye number were calculated as a function of the laser energies.
