Enhanced XUV harmonics generation from diatomic gases using two orthogonally polarized laser fields

Abstract Enhanced high repetition rate coherent extreme ultraviolet (XUV) harmonics represent efficient probe of electron dynamics in atoms, molecules and solids. In this work, we used orthogonally-polarized two-color laser field to generate strong even and odd high order harmonics from molecular ga...
