Application of primary plasma standardization to Nd-yang laser-induced shock wave plasma spectrometry for quantitative analysis Of alloys
A study was performed on a laser-induced shock wave plasma generated on high concentration Au-Ag-Cu alloys by a Q-switched Nd-YAG laser of 4.8 mJ under reduced air pressure of 2 Torr. It was found that the total emission intensity of the secondary plasma is proportional to the intensity of the...

The dynamical processes of laser-induced shock wave plasma generation at various surrounding gas pressures
A comprehensive study has been made on the dynamical process-taking place in the laser-plasma generation induced by a TEA CO2 laser bombardment on metal target and non-metal target from low to high pressures surrounding gas. In the case of metal target, pure zinc plate was used as a target and...

Contributions of sub target and confinement effects in extension of laser induced shock wave plasma spectroscopy to non-metallic targets
ABSTRACT
An comprehensiove study has been carried out for the study and extension of lases induce shock wave plasma spectroscopy (LISPS) application to non metalic soft and hard samples. For this purpose, a series of experiments were conducted to investigate the dynamical process taking place in the laser plasma generated by...

The Role of A Sub -Target in the Tea CO2 Laser-Induced Shock-Wave Plasma
A TEA CO2 laser pulse (50 mJ, 100 ns) was focused under reduced pressure on the silicone grease painted on copper plate as a sub-target with a power density of 6 GW/cm2. The comparison was made on the characteristics of the induced laser plasma between the two cases, with sub-target...
