Recently, intense research into laser plasma accelerators has achieved great progress in the production of high-energy,high-quality electron beams with Ge V-level energies in a cm-scale plasma. These electron beams open the door for broad applications in fundamental, medical, and industrial sciences. Here we present conceptual designs of an extreme ultraviolet radiation source for next-generation lithography and a laser Compton Gamma-beam source for nuclear physics research on a table-top scale.
