Saturated tabletop x-ray laser system at 19 nm

This is the authors' abstract. We don't add key points for this paper.

Saturated operation of a tabletop x-ray laser at 19 nm is demonstrated with a laser-irradiated Mo slab target. The output energy, the intensity, the near-field beam pattern, and the beam divergence are characterized. The wavelength scalability and the high brightness make it a potential tool for x-ray laser applications.
