Born around the turn of the new millennium, attosecond metrology has provided real-time insight into atomic-scale electron motions and light field oscillation, previously inaccessible to human observation. Until recently, this capability has relied on attosecond extreme ultraviolet pulses, generated and measured in complex vacuum systems. Next-generation attosecond metrology is now about to...
Broadband attosecond pulses are employed for multimodal probing of the structural response and the magnetic order in Co-Pt magnetic multilayers following ultrafast photoexcitation observing that the onset of demagnetization is time-delayed by approximately 4 fs.
In this work we use a high harmonic light source capable of producing single attosecond soft-xray pulses to study the ultrafast electronic and structural dynamics of layered semi-metals.
Attosecond time-resolved photoemission experiments on the non-centrosymmetric crystal BiTeCl provide evidence that the observed dynamics of photoemission is significantly influenced by the effective electron mass in the final states.
I will describe how the strong-field laser-matter interaction can lead to the generation of non-classical lightstates which carry the information of the ultrafast dynamics of the interaction.
Broadband attosecond pulses are used for interface-sensitive scattering spectroscopy. Using a patterned silicon structure, the response of a 1.5 nm-thick native oxide layer is isolated. Attosecond transient reflectivity measurements are then performed on this system.
