Propagation of pulsed light in an optical cavity in a gravitational field
Daniel D. Hickstein, David R. Carlson, Zachary L. Newman +2
All modern theories of gravitation, starting with Newton's, predict that gravity will affect the speed of light propagation. Einstein's theory of General Relativity famously predic…
High-resolution MHz time- and angle-resolved photoemission spectroscopy based on a tunable vacuum ultraviolet source
Lukas Hellbrück, Michele Puppin, Fei Guo +7
Time and angle-resolved photoemission spectroscopy (trARPES) allows direct mapping of the electronic band structure and its dynamic response on femtosecond timescales. Here, we pre…
Direct observation of enhanced electron-phonon coupling in copper nanoparticles in the warm-dense matter regime
Quynh L. D. Nguyen, Jacopo Simoni, Kevin M. Dorney +12
Warm-dense matter (WDM) is a highly-excited state that lies at the confluence of solids, plasmas, and liquids and that cannot be described by equilibrium theories. The transient na…
Broadband ultraviolet-visible frequency combs from cascaded high-harmonic generation in quasi-phase-matched waveguides
Jay Rutledge, Anthony Catanese, Daniel D. Hickstein +3
High-harmonic generation (HHG) provides short-wavelength light that is useful for precision spectroscopy and probing ultrafast dynamics. We report efficient, phase-coherent harmoni…
Mid-infrared frequency combs at 10 GHz
Abijith Kowligy, David Carlson, Daniel Hickstein +5
We demonstrate mid-infrared (MIR) frequency combs at 10 GHz repetition rate via intra-pulse difference-frequency generation (DFG) in quasi-phase-matched nonlinear media. Few-cycle…
Ultrafast 1 MHz vacuum-ultraviolet source via highly cascaded harmonic generation in negative-curvature hollow-core fibers
David E. Couch, Daniel D. Hickstein, David G. Winters +7
Vacuum ultraviolet (VUV) light is critical for the study of molecules and materials, but the generation of femtosecond pulses in the VUV region at high repetition rates has proven…
