“…There has been a great deal of discussion on the alignment sensitivity to strong field femtosecond laser ionization [10,[12][13][14] based on model calculations. Furthermore, it is well known that ionization of dissociating molecular ions is very sensitive to alignment [15].…”

“…In order to apply the PPT model to molecular gases, we employ the semi-empirical model of Ref. [27] with Z eff = 0.53 and 0.9 for O 2 and N 2 , respectively. For oxygen, our theory yields a long-wavelength limit of n 2 (0) = 0.7 × 10 −7 cm 2 /TW, which agrees excellently with the electronic contribution of n 2 (0) = 0.746 × 10 −7 cm 2 /TW computed in [28].…”

“…At high intensity, the predominance of plasma in signal alters the accuracy of the results as well. Results are compared with the semi-empirical model of Talepbour et al 9 relevant in the present regime. The ionization probabilities predicted by this model are calculated using the expression of the ionization rate given in Ref.…”
