From: Plasma channel formation in NIR laser-irradiated carrier gas from an aerosol nanoparticle injector

(a,b) Symbols – measured maximum ion energies (same data as in Fig. 2), lines – calculated ion energies, (a) argon, (b) helium. (c) Argon gas density calculated from the measured ion energies from the injector position scan (Fig. 3(b)). Legend indicates from which ion charge state the density was calculated. Solid line shows theoretical curve.
