Theoretical estimations of the incoherent pumping of laser-induced copper plasma

The optical pumping of laser-induced copper plasma by incoherent light a fast-discharge xenon flashlamp is proposed to enhance the stimulated emission (LIP). To study spatiotemporal evolution LIP, numerical approach based on collisional-radiative model and kinetic equations has been employed. influence total density gas temperature gain coefficient plume was studied. results show an enhancement intensity spectral lines atomic copper. This idea demonstrates that LIP low energy, may be replacement for expensive laser-pumped improvement sensitivity related diagnostics methods plasma, such as breakdown spectroscopy.
