Optical emission spectrometric diagnosis of laser-induced plasma and shock front produced at moderate pressure
نویسندگان
چکیده
We present a non-contact optical investigation of laser-induced plasma at moderate Ar pressure ranging from 1 to 100 Pa. The significant shock front and spatial fractionation among the different charged ions are demonstrated 20 collisions between Si IV ambient atoms generate distinct excited II ions, fresh III electrons dense layer. electron density peaks position front, indicating that collision yields is dominant over recombination process in region layer its immediate vicinity.

In this paper, the dynamic behavior of laser induced optical breakdown in impure water was studied by using a pump- probe technique. The plasma was induced by a 1064 nm Nd:YAG laser pulse (with pulse duration ~10 ns) in distilled water with two types of impurities: (I) a solution (highly diluted salt water as a conductor) and (II) a colloidal (TiO2 in colloidal nanoparticle form as a dielectric...
