Plasma characteristics of Ag:Al alloy produced by fundamental and second harmonic frequencies of Nd:YAG laser

Abstract

In this work, the spectra for plasma glow produced by pulseNd:YAG laser (λ=532 and 1064nm) on Ag:Al alloy with same molarratio samples in distilled water were analyzed by studying the atomiclines compared with aluminum and silver strong standard lines. Theeffect of laser energies of the range 300 to 800 mJ on spectral lines,produced by laser ablation, were investigated using opticalspectroscopy. The electron temperature was found to be increasedfrom 1.698 to 1.899 eV, while the electron density decreased from2.247×1015 to 5.08×1014 cm-3 with increasing laser energy from 300to 800 mJ with wavelength of 1064 nm. The values of electrontemperature using second harmonic frequency are greater than of1064 nm, which increased from 2.405 to 2.444 eV, while the electrondensity decreased from 2.210×1015 to 1.516×1015 cm-3 withincreasing laser energy for the same energy range.

Spectroscopic study the plasma parameters for Pb doped CuO prepared by pulse Nd:YAG laser deposition

“…All calculated plasma parameters (λ D , f p and N D ) were satisfied the criteria for the plasma. It shows that f p decrease with laser energy because it is proportional with ne, while λ D and N D increase with it such as in (Hussain and Al-Razzaq) [12]. The values of Te were obtained from the Ratio method, as shown in Figs.…”

Synthesis of Green Zno/Fe3O4 Nanocomposite by Microplasma Jet and Anti-Bacterial Agent

“…The dielectric barrier discharge, a cold plasma that may be employed at atmospheric pressure, was used in this work as a particular form of plasma. Synthesis of organic compounds with scalability and low operating costs is possible using atmospheric-pressure cold plasma [21,22].…”
