Abstract :
We have been developing a new clock laser system for an Yb optical lattice clock. The system does not include a high finesse cavity at 578 nm, but a fibre-based frequency comb, which is tightly phase-locked to a narrow linewidth Nd:YAG laser at 1064 nm. The Nd:YAG laser is phase locked to a high finesse cavity at 1064 nm made from ultra low expansion glass.
