Numerical simulations of H$_2^+$ and H$_3^{2+}$ in intense ultrashort laser pulses

We developed numerical simulation techniques to analyze H$_2^+$ and H$_3^{2+}$ interacting with intense ultrashort laser fields based on the Crank-Nicholson method and the Born-Oppenheimer approximation. We present results for the ionization probabilities and photoelectron spectrum for both molecular ions, and for circularly polarized light as well as linearly polarized light both on and off the molecular axis.
