Abstract

We consider laser systems stabilized to external Fabry-Perot silicon cavities operated at cryogenic temperatures. In order to characterize frequency stability two identical systems were created. Fractional frequency instability of individual system reached 6×10^-15 at 1 s. Different sources of noises were studied, and the dominant one now is the fluctuations of residual amplitude modulation.
