Scaling attosecond sources in two complementary directions — •Christoph M. Heyl, Piotr Rudawski, Per Johnsson, Linnea Rading, Bastian Manschwetus, Anne Hardt, Chen Guo, Johan Mauritsson, Cord L. Arnold, and Anne L’Huillier — Lund University, Sweden

Extreme ultraviolet (XUV) light sources based on high-order harmonic generation are nowadays used in many laboratories. Based on the demands set by different applications, two complementary XUV source development directions can be identified: Towards high repetition rates as required by experiments involving electron or ion detection and towards high pulse energies, needed for example for nonlinear optics in the extreme ultraviolet as well as for coherent imaging.

In this talk, an overview about status and limitations for both directions is given and a general model allowing the scalability of pulse energy and repetition rate of attosecond sources over many orders of magnitude while maintaining the conversion efficiency into the XUV [1], is discussed. Examples of attosecond beam lines at both extremes are presented. This includes two beam lines at the Lund Laser Center, a 200 kHz OPCPA-based beam line approaching the single attosecond pulse regime [2] and an intense harmonic beam line [3] as well as an attosecond beam line for the European facility ELI-ALPS [4].
