Over the past few decades, coherent broadband spectroscopy has been widely used to
improve our understanding of ultrafast processes (eg, photoinduced electron transfer, proton …

Contemporary ultrafast science requires reliable sources of high-energy few-cycle light
pulses. Currently two methods are capable of generating such pulses: post compression of …

Modern laser sources nowadays deliver ultrashort light pulses reaching few cycles in
duration and peak powers exceeding several terawatt (TW). When such pulses propagate …

Although supercontinuum sources are readily available for the visible and near infrared (IR),
and recently also for the mid-IR, many areas of biology, chemistry, and physics would benefit …

Electrons emit light, carry electric current, and bind atoms together to form molecules. Insight
into and control of their atomic-scale motion are the key to understanding the functioning of …

We report on the generation of a three-octave-wide supercontinuum extending from the
vacuum ultraviolet (VUV) to the near infrared, spanning at least 113–1000 nm (ie, 11− 1.2 …

We demonstrate noncollinear coherent two-dimensional (2D) electronic spectroscopy for
which broadband pulses are generated in an argon-filled hollow-core fiber pumped by a 1 …

Photon accelerators can spectrally broaden laser pulses with high efficiency in moving
electron density gradients driven in a rapidly ionizing plasma. When driven by a …

Broadband supercontinuum (SC) pulses in the few cycle regime are a promising source for
spectroscopic and imaging applications. However, SC sources are plagued by poor stability …

Focusing 12 fs pulses of 800 nm with moderate energy (0.35 mJ) into atmospheric-pressure
argon (Ar) gives rise to filamentation (self-focusing) and a supercontinuum with a very broad …
