Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

Laser &Photonics Reviews, EarlyView.
Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Mechanically robust biochar‐modified polystyrene foam with enhanced flame retardancy using halogen‐free additives

Polymer International, EarlyView.
Halogen‐free biocomposite polystyrene foams were fabricated via pilot‐scale supercritical CO2 extrusion using expandable graphite, melamine polyphosphate, biochar, and recycled polymer. The optimized formulation exhibited refined cellular morphology, enhanced flame retardancy (limiting oxygen index of 25%, rapid self‐extinguishing), and improved ...

Neue Einblicke in ein Schlüsselmaterial für Planetenphysik, Fusion und Materialforschung: Flüssiger Kohlenstoff

Physik in unserer Zeit, EarlyView.
Mit Hilfe der ultrahellen Röntgenpulse des European XFEL und einem speziellen Hochenergielaser konnte die Struktur von flüssigem Kohlenstoff bei Drücken von über einer Million Atmosphären und Temperaturen von etwa 7000 K bestimmt werden. Dieser Ansatz offenbarte eine komplexe Flüssigkeit mit einer wasserähnlichen Struktur und im Mittel vier ...
