Shear interferometric measurement of electron density in a laser-ablated GAP-coated nano-aluminium plasma plume

Key Points

• Laser ablation demonstrates significant changes in electron density within the plasma plume.
• Measurements indicate electron densities reaching up to 2 x 10^18 cm^-3 in the ablated region.
• Shear interferometry was employed to analyze the electron density variations in the plasma plume.
• Results support advanced techniques for measuring plasma characteristics in nanomaterials.
