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…
Unambiguous discrimination of high harmonic generation mechanisms in solids
Graham G. Brown, Rui E. F. Silva, Álvaro 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…
PHz scale spectral broadening and few-cycle compression of Yb:KGW laser pulses in a pressurized, gas-filled hollow-core fiber
Z. Pi, H. Y. Kim, E. Goulielmakis
We demonstrate efficient generation of coherent super-octave pulses via a single-stage spectral broadening of a Yb:KGW laser in a single, pressurized, Ne-filled, hollow-core fiber…
Attosecond Field Emission
H. Y. Kim, M. Garg, S. Mandal +3
Field-emission of electrons underlies major advances in science and technology, ranging from imaging the atomic-scale structure of matter to signal processing at ever-higher freque…
Mechanisms of high harmonic generation in solids
A. Thorpe, N. Boroumand, A. M. Parks +2
The long standing issue of separating resonant from non-resonant processes in extreme nonlinear optics is resolved. The theoretical formalism is applied to high harmonic generation…
