摘要
We have developed an experimental setup for picosecond time-resolved X-ray shadowgraphy and applied it to observe laser ablation. X-rays are generated by femtosecond laser focusing on a tungsten target. The pulse duration of the Generated X-rays is measured to be 33 ps. Using an optical delay system, a series of time-resolved shadowgraphs of a plasma plume, which is generated by laser ablation using 300 ps laser beam irradiation on an aluminum target, are clearly obtained by a single laser shot exposure.
