Abstract
We describe our current low-noise fiber-laser frequency comb and present measurements of its residual instability. Through a comparison with a Ti:Sapphire frequency comb, we measure residual fractional frequency instabilities (Allan deviation) of 6x10-17 at 1 second and 1.3x10-18 at 1000 seconds. This stability demonstrates that the performance of a fiber frequency comb can rival that of current Ti:sapphire frequency combs.
