Abstract :
We report on transferring 10-16-level fractional frequency stability of a “master laser” operated at 1.5 μm to a “slave laser” operated at 698 nm, using a femtosecond fiber comb as transfer oscillator. With the 698-nm laser, the 1S0 - 3P0 clock transition of 87Sr was resolved with a Fourier-limited linewidth of 1.5 Hz (before: 10 Hz). Potential noise sources contributed by the frequency comb are discussed in detail.
