Laser induced breakdown spectroscopy of copper in air
Abstract
We show the time evolution of laser induced plasma of a copper target produced in air. We also show an efficient method of recognizing the atomic emission spectra of copper by comparing the emission lines of air (78.08% N2) and the copper plasma emission in air. Prominent peak wavelengths are also compared to known emission wavelengths of copper. Relatively small deviations with respect to known emission lines that are within the calibration range show the efficiency of the method used.
