Abstract

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 such as temporal subpulse distances, energies, chirps, and phase differences. It will address the reproducibility and complexity issues that occur when employing non-deterministic algorithms in complex search spaces. The second approach, a `transition finder' algorithm uses a parameterization in the frequency domain to expose the most important transition frequencies within the laser pulse spectrum, which would not be found otherwise.
