In the ultra-relativistic regime, the laser radiation pressure induces plasma ion motion through the so called hole-boring effect, resulting in frequency widening of the harmonic spectra. This widening, analyzed analytically and validated by particle-in-cell simulations, produces a quasi-continuous frequency spectrum, a prerequisite for generating an intense single attosecond pulse. Based on the results and physical considerations, parameter maps highlighting the optimum regions for generating a single intense attosecond pulse and coherent XUV radiation are presented. Moreover, a robust plasma gating is developed to generate a super-intense phase-stabilized single attosecond pulse. The hole-boring effect limits the most efficient high-frequency emission in one laser cycle making it possible to isolate a single attosecond pulse. The generated pulse is characterized by a stabilized spectral phase ψ(ω) ≈ ±π/2 and an ultra-broad exponential spectrum up to keV region bounded by ROM scaling and CSE scaling. The unprecedented intensity highlights the potential of the isolated attosecond pulse for performing attosecond-pump attosecond-probe experiments. date: 2018 id_scheme: DOI id_number: 10.11588/heidok.00025086 ppn_swb: 1655676202 own_urn: urn:nbn:de:bsz:16-heidok-250863 date_accepted: 2018-07-04 advisor: HASH(0x55611e72af98) language: eng bibsort: TANGSUOPLASMAHIGH2018 full_text_status: public citation: Tang, Suo (2018) Plasma High Harmonic Generation and Single Attosecond Pulse Emission from Ultraintense Laser Pulses.
