| contents | We demonstrate, for the first time, that laser-accelerated protons can induce shock waves in materials. The ultra-short pulse width of laser-driven protons enables them to deposit energy instantaneously, leading to an intense thermodynamic effect that heats and pressurizes materials violently, thereby generating shock waves. In contrast, laser-accelerated electrons do not possess this capability. Our simulations and experiments reveal that the flow intensity of the proton beam, which includes information on both the proton number and pulse width, directly correlates with shock waves. This finding not only provides a new method for characterizing the high flow intensity of laser-driven protons but also expands their applications in studying extreme states of matter. |
