Unambiguous discrimination of high harmonic generation mechanisms in solids
Graham G. Brown, Rui E. F. Silva, Ãlvaro Jiménez-Galán +2
Using real-space view of high harmonic generation (HHG) in solids, we develop a physically transparent and gauge-invariant approach for distinguishing intraband and interband HHG m…

Synthesis of single-cycle pulses based on a Yb:KGW laser amplifier
Zekun Pi, Hee-Yong Kim, Eleftherios Goulielmakis
Yb:KGW lasers have been gaining increasing importance in ultrafast and strong-field physics, but their compression to the single- and sub- cycle regime remains a challenge. Here, w…

Carrier-envelope-phase-independent field sampling of single-cycle transients using Homochromatic Attosecond Streaking
H. Y. Kim, Z. Pi, E. Goulielmakis
The recent development of Homochromatic Attosecond Streaking (HAS) has enabled a novel, highly precise method for ultrafast metrology of attosecond electron pulses as well as for r…
