Isolated-attosecond-pulse generation due to the nuclear dynamics of H2+ in a multicycle midinfrared laser field.

A scheme is proposed to generate isolated attosecond pulses in the water window driven by a multicycle 2400-nm midinfrared laser field with moderate intensity interacting with H2+ molecules. Single attosecond pulses are achieved due to the charge resonance-enhanced ionization and nuclear motion by the numerical solutions of a non-Born-Oppenheimer time-dependent Schrödinger equation. Thus, the single attosecond pulse generation provides insight into the nuclear dynamics. [ABSTRACT FROM AUTHOR]
