LASER-INDUCED BREAKDOWN SPECTROSCOPY AND PLASMA CHARACTERIZATION GENERATED BY LONG-PULSE LASER ON SOIL SAMPLES
Abstract
The plasma is generated by focusing a long-pulse (80 μs) Nd:YAG laser on chromium-doped soil samples. The calibration curves are drawn using the intensity ratio of the chromium spectral line at 425.435 nm with the iron spectral line (425.079 nm) as reference. The regression coefficient of the calibration curve is 0.993, and the limit of detection is 16 mg/kg, which is 19% less than that for the case of a Q-switched laser In the method of long-pulse laser-induced breakdown spectroscopy, the laser-induced plasma had a temperature of 15795.907 K and an electron density of 2.988´1017 cm-3, which exceeded the corresponding plasma parameters of the Q-switched laser-induced breakdown spectroscopy by 75% and 24% respectively.
