An optical-frequency comb-based scheme is demonstrated that transfers a 4.5 × 10−16 fractional frequency stability from a 1,062-nm-wavelength laser to a 1,542-nm-wavelength laser. Transfer is also reported down to 4 × 10−18 at 1 s, which is one order of magnitude below that of previously reported work with comparable systems.
