Laser-plasma accelerators can accelerate electrons to relativistic energies over distances three orders of magnitude shorter than required by their conventional radio-frequency counterparts. By focusing beams from TW- to PW-class lasers into a gas target, electrons can get trapped and accelerated in longitudinal fields of several hundred GV/m. Recent breakthroughs have led to stable, quasi-monoenergetic electron beams in the GeV-scale from few-centimeter accelerator lengths. Owing to their unprecedented features, such as intrinsically ultrashort pulse duration and expected low emittance, these electron beams are perfectly suited for driving a next generation of X-ray light sources. In this talk we will discuss the basic theory and scaling laws behind these novel accelerators and end with the current experimental status and first promising applications.
