Photoelectron momentum distributions in the (x, y) plane for various IR field strengths and frequency of the probe field \(\Omega =1\) a.u. PMD is exponentiated (\(P(p_x,p_y)^{1/3}\) is shown) for improving visibility of the patterns. IR field strengths are: \(E_0=0.02387\) a.u. (a), \(E_0=0.04\) a.u. (b), \(E_0=0.0534\) a.u. (c), \(E_0=0.1\) a.u. (d), \(E_0=0.125\) a.u. (e), \(E_0=0.15\) a.u. (f). Lines show directions to low order maxima of the interference pattern.
