Description
We study photoionization of cold rubidium atoms in a strong infrared femtosecond laser field using a magneto-optical trap (MOT) recoil ion momentum spectrometer. The momentum distributions of Rb$^+$ created by absorption of two- or three-photon illuminate a dipole-like double-peak structure. The yielding momentum resolution of $0.12\pm0.03$ a.u. is achieved in comparison with calculations, exhibiting the great prospects for the study of electron correlations in alkali metal atoms through interaction with strong laser pulses.
