A precision apparatus for high harmonic spectroscopy in bulk solids
S. Mandal, P. Kumar, Z. Pi +3
High harmonic generation (HHG) in solids has emerged as a powerful spectroscopic method for resolving ultrafast electron dynamics and band structure properties across a wide range…
Deciphering the dynamics of the light-induced phase transition in VO
S. Mandal, P. Kumar, H. Y. Kim +7
Vanadium dioxide (VO) is central in the study of ultrafast photoinduced insulator-to-metal phase transitions in strongly correlated materials, and a primary candidate for next-…
Cross-process interference in single-cycle electron emission from metal needle tips
Anne Herzig, Peter Hommelhoff, Eleftherios Goulielmakis +2
Though interference from different emission channels enabled a deeper understanding of strong-field photoemission in atoms and molecules, it remained out of reach for solids. Here,…
One-stage hollow-core fiber-based compression of Yb:KGW lasers to the single-cycle regime
Z. Pi, A. B. Enders, D. Vaso +1
The generation of intense, waveform-controlled, single-cycle pulses based on Yb:KGW amplifiers is central to integrating these lasers with attosecond metrology and spectroscopy. He…
