Abstract
We present an approach for in situ dynamic four-dimensional (4D=3D space + 1D time) laser induced strong field ionization tomography, particularly suited for measuring far-from-equilibrium systems, such as supersonic and hypersonic pulsed gas jets. The inherent physical nature of strong-field interaction leads to significantly enhanced spatial resolution, with unique intensity-resolution coupling and localization of measurement depth. By employing femtosecond laser, temporal resolution is primarily limited by electronic jitter, typically to a few tens of picoseconds.
