Providing 1E-16 short-term stability of a 1.5 {mu}m laser to optical clocks


الملخص بالإنكليزية

We report on transferring 1E-16-level fractional frequency stability of a master laser operated at 1.5 {mu}m to a slave laser operated at 698 nm, using a femtosecond fiber comb as transfer oscillator. With the 698 nm laser, the 1S_0 - 3P_0 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.
