Probing broken time-reversal symmetry with tailored-light photocurrents

Daniel M. B. Lesko, Tobias Weitz, Simon Wittigschlager +4

Light-field-driven photocurrents represent a powerful tool for generating photocurrents without external bias in light-matter systems that lack inversion symmetry. While these phot…

Attosecond physics in optical near fields

Jonas Heimerl, Stefan Meier, Anne Herzig +8

Attosecond science, the electron control by the field of ultrashort laser pulses, is maturing into lightfield-driven electronics, called petahertz electronics. Based on optical fie…

Soft X-ray high-harmonic generation in an anti-resonant hollow core fiber driven by a 3 m ultrafast laser

Drew Morrill, Will Hettel, Daniel Carlson +15

High-harmonic upconversion driven by a mid-infrared femtosecond laser can generate coherent soft X-ray beams in a tabletop-scale setup. Here, we report on a compact ytterbium-pumpe…

Mid-Infrared Hyperspectral Microscopy with Broadband 1-GHz Dual Frequency Combs

Peter Chang, Ragib Ishrak, Nazanin Hoghooghi +7

Mid-infrared microscopy is an important tool for biological analyses, allowing a direct probe of molecular bonds in their low energy landscape. In addition to the label-free extrac…

Optical control of electrons in a Floquet topological insulator

Daniel M. B. Lesko, Tobias Weitz, Simon Wittigschlager +4

Light-dressed materials hold enormous potential for generating new electronic properties. The band structure resulting from light-dressing can exhibit starkly different quantum and…

A Multi-Harmonic NIR-UV Dual-Comb Spectrometer

Kristina F. Chang, Daniel M. B. Lesko, Carter Mashburn +4

Dual-comb spectroscopy in the ultraviolet (UV) and visible would enable broad bandwidth electronic spectroscopy with unprecedented frequency resolution. However, there are signific…
