#### Abstract

Ultra-stable lasers and optical frequency combs have been the enabling technologies for the tremendous progress of precise optical spectroscopy in the last ten years. To improve laser frequency stabilization beyond the thermal-noise fundamental limit of traditional room-temperature high-finesse optical cavities, new solutions have been recently developed. These being complex and often wavelength specific, the capability to transfer their spectral purity to any optical wavelengths is highly desirable. Here we present an optical frequency comb based scheme transferring a $4.5 \times 10^{-16}$ fractional frequency stability from a 1062 nm wavelength laser to a 1542 nm laser. We demonstrate that this scheme does not hinder the transfer down to $3 \times 10^{-18}$ at one second, two orders of magnitude below previously reported work with comparable systems. This exceeds by more than one order of magnitude the stability of any optical oscillator demonstrated to date, and satisfies the stability requirement for quantum-projection-noise limited optical lattice clocks.
