We find that, for the first time in the investigation of high-order harmonic generation in two color laser fields that atomic energy level structure will greatly affect high order harmonic generation.

We have now determined the atomic structure of the C. jejuni G508A flagellar filament from a 3.5-Å-resolution cryo-EM reconstruction, and show that it has 11 protofilaments. The residues in the C.
