Nanometric probing with a femtosecond, intra-cavity standing wave Open
Optical standing waves are intrinsically nanometric, spatially fixed interference-field patterns. At a commensurate scale, metallic nanotips serve as coherent, atomic-sized electron sources. Here, we explore the localized photofield emissi…

Closed-cycle noble gas recycling system for high-repetition rate high-harmonic generation Open
We present a compact closed-loop recycling system for noble and inert gases. It has been developed for an extreme-ultraviolet (XUV) frequency comb based on high-harmonic generation at 100 MHz repetition rate. The system collects gas inject…

Photoelectron tomography with an intra-cavity velocity-map imaging spectrometer at 100 MHz repetition rate Open
We present a compact velocity-map imaging (VMI) spectrometer for photoelectron imaging at 100 MHz repetition rate. Ultrashort pulses from a near-infrared frequency comb laser are amplified in a polarization-insensitive passive femtosecond …
