description | This paper carries out the spatial confinement effect on laser-induced Cu breakdown spectroscopy in a cylindrical cavity via a nanosecond pulsed Q-switch Nd:YAG laser operating at a wavelength of 1064 nm. The temporal evolution of the laser-induced plasma spectroscopy is used to investigate the characteristics of spectral persistence. The atomic spectral persistence in plasma generated from Cu with spatial confinement is experimentally demonstrated, where the results indicate that the diameter of the confinement cavity plays a very important role in the persistence of an excited neutral Cu emission line, while the depth of the confinement cavity is almost independent of Cu (I) line persistence. As the diameter of the confinement cavity increases, the persistence of the Cu (I) line in the plasma grows longer under a certain limit. The likely reason for this phenomenon is that under spatial confinement, the reflected shockwave compresses the plasma and leads to an increase in the plasma temperature and density at a certain delay time, which causes further excitation of atomic population to higher excited levels. Finally, the collision rate between particles in the plasma plume is increased. |
