Femtosecond mode-locked lasers producing visible/infrared frequency combs have steadily
advanced our understanding of fundamental processes in nature. For example, optical …

We review recent progress in coherent combining of femtosecond pulses amplified in optical
fibers as a way to scale the peak and average power of ultrafast sources. Different methods …

Geometric scaling of a Kerr-lens mode-locked Yb: YAG thin-disk oscillator yields
femtosecond pulses with an average output power of 270 W. The scaled system delivers …

ThomX is a new generation Compact Compton Source. It is currently commissioned by and
at the IJCLab (Laboratoire de physique des 2 infinis-Irène Joliot-Curie (UMR9012)) at Orsay …

The performance of fiber laser systems has drastically increased over recent decades, which
has opened up new industrial and scientific applications for this technology. However …

SESAM modelocked thin-disk lasers have recently reached new frontiers and remain the
leading technology in terms of average power and pulse energy, setting new performance …

We present a coherently combined laser amplifier with 16 channels from a multicore fiber in
a proof-of-principle demonstration. Filled-aperture beam splitting and combination, together …

Ultrafast spectroscopy in the extreme ultraviolet demands for ever-higher pulse repetition
rates and photon energies. Here, we drive cavity-enhanced high-order harmonic generation …

A conceptual design is presented of a novel energy-recovering linac (ERL) facility for the
development and application of the energy recovery technique to linear electron …

Many atomic and molecular systems of fundamental interest possess resonance frequencies
in the extreme ultraviolet (XUV) where laser technology is limited and radiation sources …
