In our experiment the 133Ba+ ions are confined in a monolithic 3D microfabricated trap [2] that provides a high degree of control of the trapping potential whilst maintaining a low heating rate. The ground level qubit transition is driven by a two-photon Raman process using a 532 nm laser. We present our novel system for driving this 10 GHz qubit transition with low phase and intensity noise. We further discuss the design of a laser-written waveguide device used for individual addressing of non-uniformly spaced ion crystals.
