Abstract :
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 1D optical lattice. The instability and the line-width of the laser system have been measured with respect to an ultrastable 657 nm diode laser with 1 Hz linewidth utilizing the transfer oscillator principle with a femtosecond fiber comb. The magnetic-field-induced clock transition of 88Sr can be used to investigate the instability of the 698 nm clock laser system at intermediate averaging times .
