Continuous-wave laser absorption spectroscopy of the thorium-229 nucleus

Abstract The low-energy nuclear transition in thorium-229 (Th-229) has been excited in thorium-doped crystals with laser light 1–3 , opening the path towards a highly stable and robust solid-state optical nuclear clock 4 . The required laser radiation at 148-nm wavelength has so...

Structural dynamics during the three-ion Coulomb explosion of highly charged CS2 in intense soft x-ray pulses

Using intense femtosecond soft x-ray pulses above the sulfur 2p edge produced by the Free-electron LASer in Hamburg (FLASH), we investigate the multiple ionization and fragmentation dynamics of CS2. We focus on the three-ion fragmentation pathways of CS2 polycations with total ch...

Transient Laser‐Induced Periodic Surface Structures Revealed by Time‐Resolved EUV Diffuse Scattering

ABSTRACT The formation of permanent laser‐induced periodic surface structures (LIPSS) on solid surfaces under impulsive laser irradiation above the damage threshold has been the subject of extensive research. Here, we report the formation of transient quasi‐periodic surface modul...
