We report on the setup and characterization of a 698-nm master-slave diode laser system to probe the 1S0-3P0 clock transition of strontium atoms confined in a 1-D optical lattice. A linewidth on the order of about 100 Hz of the laser system has been measured with respect to an ultrastable 657-nm diode laser with 1-Hz linewidth using a femtosecond fiber comb as a transfer oscillator. The laser has...
Neutral atom optical frequency standards have the potential to reach extremely high stabilities due to a high number of atoms. The frequency noise of the interrogation laser can lead to a significant degradation of the stability of a frequency standard through aliasing (Dick effect). Thus, to exploit the potential of the frequency standards, the spectral density of the frequency noise of the laser...
