We demonstrate coherent control of isotope selective fragmentation processes of potassium dimers into differing atomic isotopes using shaped fs-laser pulses. When applying evolution strategies in a feedback loop, optimizing 39 K + vs. 41 K + for diff

We present two novel types of parameterizations for optical control experiments, executed by pulse shaping and evolution strategies on the NaK system. The first is a time domain approach with a pulse parameterization with few, intuitive parameters su

We present an optimization course analysis of two coherent control experiments optimizing the ion yield in NaK and the isotope ratio of 39,39K2/39,41K2 with shaped laser pulses. As most evolutionary algorithms converge first to the most relevant para

Selective optimization of different isotopomers in an ionization process with shaped fs-laser pulses is presented for 23Na39K/23Na41K. By employing evolution strategies in a closed feedback loop a considerably high enhancement by a total factor of ab

We study specific properties of different isotopes by applying optimal control. Selective optimization for 23Na39K and 23Na41K isotopes is reported at two different central wavelengths by employing evolutionary strategies on shaped femtosecond laser

Control pulse cleaning (CPC) is the process of experimentally removing extraneous control field features in a closed-loop quantum dynamics optimization experiment. We demonstrate CPC in ionization processes in the model systems K{sub 2} and NaK by ap

We report on selective optimization of different isotopes in an ionization process by means of spectrally broad shaped fs-laser pulses. This is demonstrated for $^{39,39}K_{2}$ and $^{39,41}K_{2}$ by applying evolution strategies in a feedback loop,

The ionisation process of the NaK dimer is investigated by applying evolution strategies to optimize the spectral phase of fs pulses interacting with the molecules. The obtained optimal pulse structure with three intensity maxima is presented. As an
