摘要

X-ray emission properties of femtosecond laser-produced plasmas,es-pecially,their dependence on the atmoic numbers of target of materials,are reported. The plasma emits an ultrashort x-ray pulse that is synchronized to a femtosecond laser pulse.Utilizing this feature, we demonstrate time-resolved soft x-ray absorption measurements of optically pumped silicon near its L_II, III absorption edge by means of pump-probe spectroscopy. As a result, we observe more than a 10
