Providing 1E-16 short-term stability of a 1.5 μm laser to optical clocks
Abstract
We report on transferring 1E-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 to a Fourier-limited line width of 1.5 Hz (before: 10 Hz). Potential noise sources contributed by the frequency comb are discussed in detail.
