Electron spectroscopy at Intense Laser Fields

Research funding project
Recent developments in laser technology have opened access to light pulses with a duration below 5 fs (1 fs = 10-15 s). Such pulses consist of only a few optical cycles. When the energy of the laser light is squeezed into such a small time window, extremely high fields of several million Volts/cm are created. Atoms and molecules in such fields are instantly ionised, and electrons are liberated. The oscillating field then accelerates these electrons to high kinetic energies. Using precise control over the laser light-wave the electron trajectories can, in principle, be controlled at wish. In addition, if the phase between the light-wave and the pulse envelope is also controlled, the timing of the electron movement becomes even better and reaches the attosecond timescale (1 as = 10-18 s). Using so-called carrier-envelope phase control, which has recently become accessible, it is now possible to produce attosecond bursts of electrons, and attosecond ultraviolet and x-ray emission. The results of the present research project have strongly contributed to this kind of research.
