Abstract

High-order harmonics generated by two coaxial Gaussian beams focused at different sides of the target are focused at different points. Using this spatial structure of the harmonics one can select one harmonic from the others with a pinhole situated in the focus of the harmonic. The focusing of the harmonic is much sharper, than under single-beam generation. This provides obtaining harmonic field with greater intensities.
