Abstract: (647 Views)
In the present research, the spatio-temporal evolution of the flashlamp-pumped laser-induced copper plasma by a collisional-radiative model based on kinetic equations has been calculated to describe the mechanism of the laser oscillation. The gradient of total population density and the stimulated emission intensity at 510.5 and 578.2 nm of Cu atoms and their pumping transitions were simulated by a four-levels system. Results confirm the enhancement of stimulated emission of the active medium of the Cu plasma at forward and backward directions. This noble idea showed that the flashlamp-pumped laser-induced plasma (LIP) can be replaced with more expensive laser-pumped LIP for improvement of the LIBS method.
