High-Order Harmonic Extension and Generation of Single Isolated Attosecond Pulse in Hydrogen Gas by Using Plasmonic Field Enhancement

Abstract- By using numerical solving of the 1D time dependent Schrödinger equation, we present theoretical study of high-order harmonic generation using plasmonic field enhancement. We show that the strong inhomogeneity feature of field enhancement, plays an important role in HHG process and as a result we obtain a short isolated pulse.
