Simulation of bound state population. a The integral population of all ⁸⁷Rb bound states after a Gaussian laser pulse of 1022 nm wavelength and 300 fs full width at half maximum (FWHM) duration is shown with respect to the peak intensity I₀ (red solid line). Population of the 5²S ground state (blue) and 5²F resonant state (yellow) shows that after the laser pulse the population is mainly transferred from the ground state into the continuum and into the 5²F state. The final 5²F population oscillates with the peak intensity. b Time-dependent population of the 5²S ground state (blue) as well as the 5²F (yellow) and 4²D (purple) excited states during the laser pulse of I₀ = 7 × 10¹⁰ W cm⁻² peak intensity (gray dashed line)
