  Rydberg atoms are in the focus of intense research due to the peculiar
properties which make them interesting candidates for quantum optics and
quantum information applications. In this work we study the ionization of
Rydberg atoms due to their interaction with a trapping laser field, and a
reaction microscope is used to measure photoelectron angular and energy
distributions. Reaction microscopes are excellent tools when brandished against
atomic photoionization processes involving pulsed lasers; the timing tied to
each pulse is crucial in solving the subsequent equations of motion for the
atomic fragments in the spectrometer field. However, when used in pump-probe
schemes, which rely on continuous wave probe lasers, vital information linked
to the time of flight is lost. This study reports on a method in which the
standard ReMi technique is extended in time through coincidence measurements.
This is then applied to the photoionization of $^6$Li atoms initially prepared
in optically pumped $2^{2}S_{1/2}$ and $2^{2}P_{3/2}$ states. Multi-photon
excitation from a tunable femtosecond laser is exploited to produce Rydberg
atoms inside an infrared optical dipole trap; the structure and dynamics of the
subsequent cascade back towards ground is evaluated.
