We describe our experiment which evaluates frequency shifts due to collisions in a 1-D optical lattice clock with 88Sr. The atoms in the lattice are probed on the 1S0-3P0 transition which is highly forbidden but becomes weakly allowed by applying a static homogeneous magnetic field which mixes 3P1 to the 3P0 state. Using the method of interleaved stabilization, we have quantified the density dependent...
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...
