Abstract :
Two coherent 1.5 μm frequency combs are transferred to 3.4 μm by difference-frequency generation with a 1064 nm cw laser. From a multi-heterodyne measurement, the residual linewidth between the comb teeth is resolution-limited at 200 mHz. Work of the U.S. government, not subject to copyright.
