Journal ArticleDOI
Linking high harmonics from gases and solids
Giulio Vampa,T. J. Hammond,Nicolas Thiré,Bruno E. Schmidt,François Légaré,C. R. McDonald,Thomas Brabec,Paul B. Corkum +7 more
TL;DR: It is found that solid-state high harmonics are perturbed by fields so weak that they are present in conventional electronic circuits, thus opening a route to integrate electronics with attosecond and high-harmonic technology.
Journal ArticleDOI
Theoretical Analysis of High-Harmonic Generation in Solids
TL;DR: The analysis indicates that the interband current neglected so far is the dominant mechanism for HHG, and saddle point analysis in the Keldysh limit yields an intuitive picture of interband HHG in solids similar to atomic HHG.
Journal ArticleDOI
All-Optical Reconstruction of Crystal Band Structure
Giulio Vampa,T. J. Hammond,Nicolas Thiré,Bruno E. Schmidt,François Légaré,C. R. McDonald,Thomas Brabec,Dennis D. Klug,Paul B. Corkum,Paul B. Corkum +9 more
TL;DR: This work demonstrates an all-optical technique to reconstruct momentum-dependent band gaps by exploiting the coherent motion of electron-hole pairs driven by intense midinfrared femtosecond laser pulses, and identifies the split-off valence band as making the greatest contribution to tunneling to the conduction band.
Journal ArticleDOI
Semiclassical analysis of high harmonic generation in bulk crystals
TL;DR: In this paper, the authors investigated high harmonic generation in solids and found that interband emission is dominant for the midinfrared laser driver frequencies, whereas intraband emission dominates the far-infrared range.
Journal ArticleDOI
Plasmon-enhanced high-harmonic generation from silicon
Giulio Vampa,Giulio Vampa,Behnood G. Ghamsari,Behnood G. Ghamsari,Saba Siadat Mousavi,T. J. Hammond,Anthony Olivieri,E. Lisicka-Skrek,A. Yu. Naumov,David M. Villeneuve,André Staudte,Pierre Berini,Paul B. Corkum,Paul B. Corkum +13 more
TL;DR: In this article, the authors used an array of monopole nano-antennas to demonstrate plasmon-assisted high-harmonic generation directly from the supporting crystalline silicon substrate.
