Diffusion Mapping
The objective of our research is to explore the possible application of the diffusion mapping method to strong field control of chemical processes. However, our preliminary test bed is diffusion mapping to find the pulse shape that will maximize the amount of doubled light exiting the BBO crystal. A pulse shaper, coupled with a genetic algorithm, will be used to seek out the proper pulse shape to perform the optimization of the SHG signal.

Significant progress has been made towards our preliminary goal of diffusion mapping of SHG. First, we have written the computer code necessary to do the analysis of the data. Second, we have investigated both random pulses, directed pulses and the corresponding diffusion maps. Preliminary results for the doubled light experiment using a BBO crystal suggest that diffusion mapping is an effective tool for revealing purpose related structures in pulse shape space.
