The ionization of Ar and Xe in a dichroic pulsed laser field, comprising the fundamental and second harmonic of a Ti:sapphire laser, was studied. The ion yield was found to depend on the angle between the polarization vectors of the two fields. The dependence was explained by proposing a model that considered the ionization process to be resulting from the action of two independent mechanisms, namely quasi-static tunnelling and multiphoton ionization. 

Multi-electron dynamics investigated with strong-field tunnelling and XUV photoionization

Tunnel ionization initiated by intense ultrashort laser pulses is highly nonlin­ ear with intensity. Few-cycle pulses can therefore be used to control electron dynamics on subfemtosecond timescales.

TLDR
The production of He[sup +] and He[Sup 2+] by a 160 fs, 780 nm laser has been measured over an unprecedented 12 orders of magnitude in counting range and the NS yield is found to scale with the ac-tunneling rate for the neutral, even when tunneling is not the dominant ionization pathway.

It is shown theoretically and experimentally that one possible process limiting the SHG efficiency at low as well as at high intensities is the modulation of the phase of the fundamental wave.
