Theory of laser induced strong-field ionization tomographic imaging

Laser-induced strong-field ionization tomography (LISFIT) is an emerging spacetime tomographic modality with the potential to advance imaging capabilities. To fully harness its power, a robust theoretical framework is essential. This work delves into the fundamental physics of strong-field ionization and its implications for tomographic imaging. Our analysis reveals an operational regime with significant resolution enhancement and unique intensity-resolution coupling, alongside localization phenomena rooted in the physics of strong-field interactions. We further identify a trade-off between resolution, localization extent, and signal-to-noise ratio, providing critical insights for optimizing experimental parameters.
