Paper Abstract

An analytical isentropic compression model for condensed matter is reported, which can provide explicit solutions for isentropic compression fields. To demonstrate this model, a laser-direct-driven ramp compression experiment is performed using an 8-ns, 740-J temporally shaped laser, achieving a peak pressure of 425 GPa in solid aluminum, which value exceeds all previous experimental results. The primary application suggests that this model can function as an important prototype for ramp compression experiments, and the temporally shaped laser direct-driven ramp compression technique can form a practical method to achieve isentropic compression.
