Abstract: An experimental approach to the near- and supercritical thermodynamic states of metals under dynamic control over a thermodynamic trajectory of pulsed laser heating was developed. Proof-of-concept experiments on aluminum confined by organic and nonorganic films were conducted, and high-energy states with temperatures up to 10⁴ K and pressures up to 600MPa were obtained.

Keywords: pulsed laser heating, laser ablation, supercritical states of metals, critical point.
