femtosecond laser,shock wave

Solid material changes directly to plasma, not via the liquid or gas state, due to ablation when the solid material is irradiated with a femtosecond laser pulse of more than 1014 W/cm2. The shock wave is driven by the rapid expansion during the ablation and propagates through the solid. In-situ XFEL diffraction measurements during femtosecond laser ablation and dry laser peening as an application of the femtosecond laser shock compression will be explained in this presentation.
