Abstract
We propose a promising scheme to produce extreme ultraviolet frequency combs through high-harmonic generation with a surface-enhanced optical field. High harmonics are generated in a wavelength-scale spatial region and show a noticeable emission probability at an angle around 10° relative to the surface. This can be further controlled with an additional static electric field or polarization-gated scheme, leading to enhanced energy conversion efficiency and extra even-order harmonic generation.
