Few-cycle pulses at wavelengths longer than 10 µm are important for fundamental studies of the non-equilibrium properties of condensed matter, i.e., solids and liquids, and exhibit a high application ...

Intense ultra-short pulses have sophisticated generation processes, complex metrology schemes and their applications are ubiquitous, spanning atomic-molecular physics, chemistry, material science, ...

Scientists at the University of Oxford have unveiled a pioneering method for capturing the full structure of ultra-intense laser pulses in a single measurement. The breakthrough, published in close ...

Physicists at the University of Oxford have unveiled a “pioneering” method for capturing the full structure of ultra-intense laser pulses in a single measurement. The breakthrough, a collaboration ...

A time-dependent electric current emits an electromagnetic wave, a basic physical effect exploited in telecom antennas. Transferring this mechanism to the ultrashort length and time scales of the ...

High harmonics: a NIR pulse (red) is focussed, and high harmonics are generated in a gas jet that is placed before or behind the NIR focus. The generated XUV light (violet) has a size and divergence ...

A new light source generates ultrashort infrared pulses at wavelengths around 12 µm with previously unattained peak intensity and stability. First experiments in vibrational spectroscopy on water ...
