Comparison of experimental data with theoretical predictions.
The theories are scaled using a spline fitting procedure. For the ADK fit, A = 0.18 and η = 3.89, with χ2 = 0.41. For the TDSE fit, A = 0.42 and η = 1.59, with χ2 = 0.25. Inset: A comparison of the probability of ionisation for a single atom using the ADK theory against the focal volume averaged (FVA) ADK application as described in the main plot. It is observed that the sharp change in ionisation rate at ~1.5 × 1013 W/cm2 observed in the FVA data corresponds to the point where the ionisation probability of a single atom is approximately 80%. The black dashed line is provided as a guide for the eye.
