Light shift of atomic levels induced by an intense off-resonant light field can be employed to measure properties of the atomic system. In particular it opens a path to measure atomic parity violation. This work focusses on creating an intense laser field and the overlapping of this field with a localized Ba+ ion in a hyperbolic Paul trap. The design of the optical system is described and the procedure to align the focussed laser beam with the ion is discussed. The succesful alignment results in a detectable optical transition rate with a large detuning of 4 nm from the resonance. The optical signal from a single trapped Ba+ ion was analysed in terms of frequency resolution which provides the sensitivity to the light induced shifts. The project was carried out at the Van Schwinderen Institute in the context of an experiment which aims at measurements of atomic parity violation in a single trapped Ba+ and Ra+ ion.
