报告摘要：

We present our project to make a laser working in the soft x-ray range based on the interaction of an X-FEL beam with a multilayer. Two conditions are required to build a laser: an optical cavity and a population inversion. The first condition can be achieved with periodic multilayers designed as optical components to work in the soft x-ray range. In this case the multilayer acts both as the active medium for the lasing emission and the optical cavity. The second condition can be realized owing to the large pumping power delivered by an X-FEL, leading to a lot of ionizations in the core levels of the atoms present within the multilayer. We present our calculations showing that such a lasing scheme is feasible.
