要旨:
The invetigation of multiphoton ionization (MPI) in a purely perturbative regime at
low intensities requieres fast data acquisition. Combining a 100 MHz frequency comb
(FC) amplified in a femtosecond enhancement cavity (fsEC) with intra-cavity velocity
map imaging (VMI) technique enables such measurements. This bachelor thesis
deals with tomographic reconstruction of photoelelectron momentum distrubutions,
without the need of any symmetry assumptions. Therefor, a suitable filtered backprojection
(FBP) algorithm was presented and the VMI was successfully characterized.
Due to high intensity sensitivity of MPI a polarization dependency of the intra-cvity
enhancement was investigated and slight deviations of a few percent were found.
