Study of matrix effects in laser plasma spectroscopy by shock wave propagation

Physics of Plasma in Laser-Induced Breakdown Spectroscopy

“…The collection angle of the fiber end allows gathering of light from a broad volume of plasma plume. The use of optical fiber bundles has also been proposed for the simultaneous acquisition of spectral emission from different regions inside the plasma plume [91]. Various configurations have been proposed, including the use of two optical fibers [92][93][94] one for delivering the laser beam and one for collecting the plume emission or one single fiber for both the purposes [95][96].…”

Laser breakdown in alcohols and water induced by λ= 1064 nm nanosecond pulses

“…Laser induced breakdown mechanism in air and in solids is well established [7][8][9][10][11][12]. The hydrodynamic characteristics of laser induced breakdown in water, as well as in some other liquids, have also been studied [8,[11][12][13][14][15][16][17][18][19][20][21].…”

Determination of Ca in breakfast cereals by laser induced breakdown spectroscopy

“…This is due to variations in both the ablation and laser plasma interaction processes, resulting also in possible variations of plume expansion in the background gas. As a result, different excitation and ionization levels of plasma species are achieved (Anzano, Villoria, Ruíz-Medina, & Lasheras, 2006;Krasniker, Bulatov, & Schechter, 2001). This signal feature makes it difficult to find the appropriate calibration standards for the LIBS methods.…”
