Abstract Plasma generated by dual pulsed synchronized laser ablation onto two perpendicular graphite targets in vacuum was analyzed by two-color interferometry and fast photography. The delay between the firing of the lasers was varied up to 5 μs. Electron and neutral densities values at 0.5 mm from the second pulse target were 1.3 × 10 18 cm −3 and 3.0 × 10 19 cm −3 respectively.
