A traveling-wave Stark decelerator has been shown to be useful to slow down SrF molecules, with recent (2016) experiments showing a reduction by 85% of the initial kinetic energy of such a beam. For future experiments to find the electron electric dipole moment (eEDM), a switch from SrF to BaF is required. In this thesis, the production and detection of a BaF beam are discussed. The production process involves cryogenic sources to reduce the initial momentum of the much heavier BaF molecules. The focus of this work is on the setup used to lock the detection lasers to their required frequencies. Such a setup was built to lock a diode laser to a wavelength of 860 nm with a long term stability of 2 Mhz. This new setup has been compared to the old one used to lock the SrF detection laser and recommendations were made to improve it.
