Abstract
We introduce recent advances in the techniques of generating laser-driven ultrashort x-ray pulses. We demonstrate that the intensities of the generated x-ray pulses can be enhanced by arranging a prepulse prior to the main laser pulse and by the nanostructure prepared on the surface of the target materials. Through the pump-and-probe EXAFS measurements, we probe in real time the melting process of the solid Al induced by the intense laser pulses having the fluence below the ablation threshold.
