Experimental study of laser-induced plasma: Influence of laser fluence and pulse duration

Morphology and characteristics of laser-induced aluminum plasma in argon and in air: A comparative study

“…Such arrangement of species in successive layers within a nearly spherical plasma morphology corresponds to the consequence of LSC wave as we discussed in our previous works [10,11]. In the LSC wave model, the layer of shocked ambient gas We can see that the aluminum vapor in air presents a larger extent than that in argon, which is consistent with the larger compressibility of the air mentioned above.…”

“…According to the results presented in our previous works [7][8][9][10][11], laser-supported absorption waves (LSAW) during the post-ablation interaction, especially the laser-supported consumption (LSC) wave and laser-supported detonation (LSD) wave can greatly influence and modify the morphology of the plasma. Such influence is particularly pronounced for infrared (IR, 1064 nm) ns laser ablation at relatively high fluence (> 150 J/cm 2 ).…”

Ablation plume structure and dynamics in ambient gas observed by laser-induced fluorescence imaging spectroscopy

“…From the observed emissivity distributions, several researchers have estimated the cross-sectional number density distributions of highly excited atoms using Abel inversion [29][30]. In contrast, for the study of the distribution of ground state atoms in a plume, LIF and absorption imaging techniques have been employed.…”

Direct determination of Ti content in sunscreens with laser-induced breakdown spectroscopy: Line selection method for high TiO 2 nanoparticle concentration

“…An optical fiber was installed with its input end on the image of the plasma. The aperture of the fiber was 50 μm of diameter, much smaller than the size of the plasma of the order of about 2 mm [13]. The detection was thus localized at a specific part of the plasma.…”
