Title: Single-attosecond pulse generation using a seed harmonic pulse train

Abstract

We propose a method to generate a single-attosecond soft-x-ray or extreme ultraviolet pulse by use of two infrared (IR) laser pulses of different wavelengths, neither of which alone is sufficiently short for single-pulse generation. Our simulations based on the time-dependent Schroedinger equation show that, when a harmonic pulse train generated by one IR laser field is superposed with the other driving laser and applied to a target atom, only one pulse in the train significantly boosts harmonic generation and acts as an attosecond enhancement gate for isolated pulse generation.
