Super-intense single attosecond pulse generation from plasma self-generated gate — •Suo Tang, Naveen Kumar, and Christoph h. Keitel — Max Planck Institute for Nuclear Physics, Saupfercheckweg 1, 69126, Heidelberg, Germany

We present the generation of an isolated super-intense pulse with extremely short duration (<20 as) in the interaction of solid with ultra-relativistic laser. The generated pulse is characterized with stable phase ψ=±π/2 at the pulse center and slowly decaying exponential spectrum transiting from ROW scaling to CSE scaling. Hole boring effect, as a robust plasma self-generated gate [1], isolates the most efficient pulse emission at the beginning of ion motion by producing an ultra-broadband coherent spectrum. Collision effects also contribute to the attosecond pulse isolation by affecting the intensity of the generated harmonics. Radiation reaction force reduces the phase fluctuation in high frequency components and thus can also affect the intensity of the emitted attosecond pulse.
