Calculate of Plasma Parameters Produce from Copper Target using Boltzmann-Plots Method

Abstract

This research shows the optical emission spectroscopy (OES) of copper (Cu) plasma. Copper plasma was induced using a Q-switched Nd: YAG pulsed laser with the following parameters: fundamental wavelength (1064[Formula: see text]nm), energy range (400–600) mJ, frequency (6) Hz and laser pulses (10–30 pulses). Many characteristics of plasma, such as electron temperature ([Formula: see text]), electron density ([Formula: see text]), Debye length ([Formula: see text]) and plasma frequency ([Formula: see text]), have been determined via spectroscopic examination. Electron temperature ([Formula: see text]) ranged from (1.47–1.759)[Formula: see text]eV, and electron number density ([Formula: see text]) ranged from (6.3–11.4) [Formula: see text][Formula: see text]cm3. The picture of the site of laser bombardment of copper (Cu) metal displays three diameters or circles, each of which has a distinct hue. The laser’s interaction with the copper metal is seen via laser ablation, and the influence of the increasing energy of the laser is seen here during the spectroscopic diagnostic and the process of metal bombardment, leading to the formation of a crater.
