Femtosecond laser pulses, characterised by their ultrashort duration on the order of 10 –15 seconds, have revolutionised the way we probe and manipulate matter. When these pulses propagate through air ...

The research group Femtosecond Dynamics at the Institute of Experimental Physics at TU Graz have demonstrated for the first time that laser-assisted electron scattering can also be observed in ...

Physicists routinely exploit femtosecond light pulses to track the movement of atoms in molecules, and are now developing sources that emit even shorter bursts of X-rays to study and control the ...

Recent advances in femtosecond optical vortices (FOVs)—characterized by helical wavefronts and high peak power—have enabled breakthroughs in attosecond vortex generation and 3D chiral microfabrication ...

The bandgap defines how insulators absorb light and conduct electricity. XUV high-harmonic interferometry now lets researchers track its femtosecond dynamics. (Nanowerk News) The bandgap, i.e. the ...
