| Yhteenveto: | The work presented in this thesis concentrates on the construction and development
of a Fabry-Perot Interferometer (FPI).
Resonance ionization spectroscopy (RIS) is a powerful technique for the extraction
of nuclear structure, namely nuclear spins, moments and changes in mean-square
charge radii. However, due to the pulsed nature of the laser, the technique may be
limited by the laser linewidth to low resolution spectroscopy. This thesis presents the
construction and characterization of a Fabry-Perot Interferometer in order to measure
the laser linewidth and to calibrate the wavelength of a pulsed Ti:Sapphire laser in
"Narrowband" mode (<1 GHz). The FPI has been directly utilized in the measurements
of optical transitions via resonance ionization spectroscopy of copper.
