title: Cavity-enhanced noncollinear high-harmonic generation for extreme ultraviolet frequency combs.
abstract: We investigate an efficient scheme to generate and outcouple extreme ultraviolet frequency combs based on cavity-enhanced noncollinear high-harmonic generation. Our numerical results show that phase matching plays a crucial role for high energy conversion and output-coupling efficiencies, which strongly depend on the crossing angle, ionization probability, and initial atomic density.
