Laboratory Website Attosecond Science Research Team. 2017-02-08 · Finally I will describe our plans for the transition from FEL R&D to science and discuss the roadmap to attosecond science with LCLS-II. Speaker: Agostino Marinelli, SLAC Program Description Time-resolved experiments at the attosecond scale hold great promise for understanding ultrafast electron dynamics in molecules, as well as the role of electron coherence in chemistry. The emphasis of the research in the last 20 years is in the scientific areas of AMO physics, attosecond science and strong field laser-matter interactions. Scientists have been developing sources of light with ever-shorter pulse durations, in order to study motion in Attosecond pulses were first produced in 2001.

Although this behaviour has been studied for many years, it is still not completely understood. We use the simplest atoms of all, hydrogen atoms, to make precise measurements of attosecond dynamics. 2019-01-21 On the other hand, those nonlinear processes in the XUV region is indispensable for progress of attosecond science including attosecond atomic/molecular physics and chemistry, because it is very useful for investigating ultrafast phenomena directly in attosecond time scale. 2010-04-16 2021-01-29 Attosecond Science Group cfel-atto.

The detailed measurement and resolution of, reconstruction of, and even active manipulation of the dynamics of valence electrons–and hence of real world chemistry in action–is at last becoming feasible , , , , , , , , . These new experimental capabilities have both made more urgent and allowed to at last address the old, but still unresolved question of tunnelling time. Attosecond science offers formidable tools for the investigation of electronic processes at the heart of important physical processes in atomic, molecular and solid-state physics. In the last 15 years impressive advances have been obtained from both the experimental and theoretical points of view. The Attosecond Science team applies the Parametric Waveform Synthesis (PWS) technology, developed jointly with UFOX's Optical parametric synthesiser team, to the generation of attosecond pulses via high-harmonic generation (HHG) in a gas jet. Attosecond science works somewhat like sonar or 3-D laser mapping, but at a much smaller scale.

Conference was organis Attosecond technology builds on, and contributes to, important historic directions in science. For this reason, the science has the depth to yield important discoveries for a long time. Unfortunately the title “attosecond” science biases us to think mostly about dynamics but many of the most important applications of “attosecond technology” may not be related to dynamics at all.

Conference was organis How to get the very short pulses needed for attosecond science wasn’t completely clear, he says, “but it seemed like it should only be a technical challenge.” Compressing light For light compression, Chini says, researchers commonly use self-phase modulation in noble-gas-filled hollow-core capillary fibers to generate a broad spectrum, and then compress the pulses using chirped mirrors. 2020-07-13 A.

Attosecond science, a recently established research field that is overarching, relating the various traditional subjects (physics, chemistry, biology, material sciences, etc.), holds strong promise to this regard. Regarding the connection of Quantum optics with Attosecond Science, a theoretical quantum optical description of strong-field laser-atom interaction" (Scientific Reports 6, 32821 (2016)) has been developed, followed up by the experimental development of a "Quantum optical XUV spectrometer" (Nature Comm. 8, 15170 (2017)). http://www.weforum.org/ Quantum Attosecond Science. QUANTUM PICTURE. A strong oscillating laser field can create modulations in the electron wavefunction. The wavepacket can expand over ~10-100 hydrogen-atom sizes away from the parent ion.
