Spectroscopic study of the plasma created by interaction between a TEA CO2 laser beam and a Ti target in a cell containing helium gas

IR laser-induced metal ablation and dielectric breakdown in benzene

“…We note that the pulsed IR laser-induced plasma in metals (and concurrent metal ablation) has not previously find any use as a deposition technique, although the process itself has been examined for Zn [44,45] and Ti [46][47][48] and the UV and VIS laser-induced ablation of metals has been reported [49][50][51].…”

Analytical Studies of Polychromes by Time‐Integrated Laser‐InducedBreakdown Spectroscopy

“…LIBS relies on the detection of the ablation plume produced in the laser interaction with the sample. For a diversity of materials and laser excitation sources, it has been observed that light from the ablation plume emission typically lasts for less than 10 s after the ablation event [6][7][8]; time resolved LIBS experiments have shown that during the first hundred ns, the atomic emission lines are superimposed on a strong background continuum, which results in a poor signal-to-noise ratio and hinders the detection of weak features [1,9]; broadening of the spectral lines by the Stark effect has also been observed to take place at short times, decreasing remarkably after the first microsecond [10]. For this reason LIBS is more commonly used with time resolution, requiring the use of expensive gated detectors with enhanced sensitivity.…”
