    "abstract": "We investigate pump-dump photoassociation of ultracold molecules with\namplitude- and phase-modulated femtosecond laser pulses. For this purpose a\nperturbative model for the light-matter interaction is developed and combined\nwith a genetic algorithm for adaptive feedback control of the laser pulse\nshapes. The model is applied to the formation of 85Rb2 molecules in a\nmagneto-optical trap. We find for optimized pulse shapes an improvement for the\nformation of ground state molecules by more than a factor of 10 compared to\nunshaped pulses at the same pump-dump delay time, and by 40% compared to\nunshaped pulses at the respective optimal pump-dump delay time. Since our model\nyields directly the spectral amplitudes and phases of the optimized pulses, the\nresults are directly applicable in pulse shaping experiments.",
