Abstract

Numerical solutions of the time-dependent Schroedinger equation for the molecular ion H₂⁺ in intense laser fields, I approximately equals 10¹⁴ W/cm² and long wavelengths, (lambda) equals 1064 nm lead to the conclusion that electron motion can be controlled at these high intensities as a function of laser phase difference for two color photoionization, either in (omega) + 3(omega) or (omega) + 2(omega) combinations. A new phenomenon, charge resonance enhanced ionization, CREI, has been discovered and can be rationalized in terms of a tunneling model. Finally, the ionized electron is rescattered by the molecular ion core at long laser wavelengths, thus suggesting the use of such rescattering to study laser- induced electron diffraction, LIED, in order to 'clock' time-dependent nuclear dynamics.
