Transfer of Spectral Purity Between Four Wavelengths at the 10-8 Level

We present the results of the operational transfer of spectral purity at LNE-SYRTE. The frequency chain offers the possibility to transfer spectral properties in single-branch configurations between 698 nm, 1062 nm, 1160 nm and 1542 nm, with added noise in the 10-8 range. In this paper, we will discuss the results, we will analyze the impact of the different sources of noise and we will present the architecture of the frequency chain.
