Abstract
We use the method developed in [1] to derive simple expressions for strong-field ionization rates of molecules, as a function of their alignment with respect to the electric field. Our analytical expressions offer transparent physical interpretation, and demonstrate the connection between the geometry of the ionizing molecular orbital and alignment-dependent ionization rates, including the sensitivity of the angular patterns to the field strength. We also show how static tunnel ionization rates can be generalized to describe the subcycle ionization dynamics in oscillating laser fields.
