Gas jet structure influence on high harmonic generation
Significance of output:
This paper demonstrates an order of magnitude increase in the XUV flux available from a light source based on high harmonic generation (HHG).
HHG sources can produce lab-scale soft Xrays whose temporal and coherence properties can rival those of synchrotrons. Real-world applications for soft Xrays, like biological imaging or lithographic mask inspection require high photon fluxes, an issue for many HHG techniques. The order of magnitude flux increase demonstrated here will directly improve soft Xray imaging, and the technique of imaging of fluorescence from excited ions represents a new way to look at gas jet diagnostics.
