چکیده
Abstract A nanosecond Atmospheric Pressure Plasma Jet (ns-APPJ) operated in pure nitrogen is studied by spatially and temporally resolved Optical Emission Spectroscopy (OES) complementing the companion paper Kuhfeld et al. PSST 2023 XXXX , where discharge investigated means of Particle-in-Cell/Monte Carlo Collisions (PIC/MCC) simulations fluid models. Two temporal phases evolution are identified: a fast breakdown quasi-DC phase. It shown that during phase several ionization waves develop, while after has structure similar to DC glow discharges, agreement with modeling predictions. The results measurements spatial-temporal dynamics light emission compared distribution densities N 2 + (B Σ u ) (C 3 Π states reconstructed from PIC/MCC simulations. good demonstrated.

Effect of voltage and capacitance in nanosecond pulse discharge enhanced laser-induced breakdown spectroscopy.
The laser ablation fast pulse discharge plasma spectroscopy (LA-FPDPS) technique has demonstrated its validity to enhance the optical emission of laser-induced plasma. It has the potential to improve the performance of traditional LIBS measurement. Very recently, LA-FPDPS with a nanosecond pulse discharge circuit has been developed, which has a better capability to enhance the optical emission ...
متن کاملNanosecond polarization-resolved laser-induced breakdown spectroscopy.
It is shown that the continuum emission produced in the ablation of an Al target with nanosecond laser pulses is much more strongly polarized than the discrete line emission. This effect may be utilized to improve the resolution of the laser-induced breakdown spectroscopy spectrum by using a polarizer to filter out the continuum background. The effects of laser fluence and focal position are al...
