In this paper we describe a new laser system we have developed to probe the ultra-narrow 1S0 -> 3P0 clock transition at 578 nm in neutral ytterbium. The yellow light is produced by sum frequency generation in a periodically-poled waveguide. With approximately 100 mW each from a fiber laser and Nd:YAG laser, we produce 10 mW of visible light. Stabilization of the laser to a resonance of a high finesse, environmentally-isolated cavity has enabled resolution of spectroscopic features as narrow as 5 Hz.
