Final Activity Report Summary - ADAM (Advancing attosecond metrology)
The basic goals of this project were to advance the basic tools of attosecond metrology in order to allow study of the electronic motion on its natural time scale. These goals have been reached within this project to a very good extend. The researcher and his colleagues have been able to demonstrate for the first time advances as the following: In the context of this project, we developed a method for generating ultrabroadband coherent light which is based on the self channelling of few cycle light pulses in highly pressurised noble gasses. This simple method has yielded for the first time light spectra that span the entire range from 250 nm to 1000 nm that is from the ultraviolet to the IR, with very high efficiency. With this light we will be able in the future to generate waveforms of light capable to control the motion of electron in molecules and solids by exerting strong forces on a very short time scale. Selecting only the ultraviolet part of this spectrum was the way to generate for the first time sub 4 femtosecond pulses in the ultraviolet. These pulse are to only to allow ultrafast electronic excitation of molecular systems Another major achievement was the generation of isolated attosecond pulses in the sub 200 as at high energy and flux for the first time. (Published in Science). We further advanced this technology and recently we were able to break yet another barrier in ultrafast optics. The generation of sub 100 attosecond pulses. These pulses will permit for the first time real time tracing of the electron motion in atoms and molecules.

Project objective
Dynamic studies of ultra-fast atomic and molecular processes in an attosecond time scale, call for tools and techniques with extremely high temporal resolution. Recent advances in ultra-fast optics have made possible the experimental demonstration of pulses lasting only a few hundreds of attoseconds in the XUV range of the spectrum opening the door to attophysics.A series of proof-of- principle experiments, have demonstrated that concepts utilizing these pulses, could push the frontiers of modern spectroscopy, allowing time resolved studies of ultra-fast phenomena in atoms and molecules establishing the so- called Attosecond Metrology. The principal objective of this project, is to advance the state of the art of these tools by generating ready to use isolated attosecond pulses with even shorter pulse durations 100 as at even higher energies reaching the X-ray regime 500eV-2 KeV allowing studies in the interior of the atoms, where the dominant process have remained dynamically unexplored up to date. To reach these objectives, novel developments in laser light sources, laser light metrology based on the existing attosecond pulses, and x-ray optics will play a key role.
