partOf Configuration for diagnostic setup: laser beam focused by a spherical plano-convex fused-silica lens (focal length: 30 cm) in a plane approximately 1 cm behind the plasma jet; fluorescence signal detected perpendicular to the laser beam direction using an iCCD camera, after passing two achromatic lenses (focal length: 80 mm) and an interference filter (central wavelengths λ_O = 845 nm, λ_H = 656 nm, λ_Xe = 835 nm, λ_Kr = 825 nm, band width ∆λ = 10 nm).
