  • Waist measurement: clock laser: 23.12.16: Waist position was not in the center of the chamber
  • Waist measurement: clock laser: 23.01.17: collimation of clock laser
  • Measurement: 3P1 splitting: 24.01.17 new frequency of double pass aom: 104.8365 MHz
  • Waist measurement: clock laser: 30.01.17: clock laser focused 174um @ 20.4 cm; atoms @ 26.5cm
  • 2nd homogenous Coils with Copper band: 06.02.17
  • Reduced lattice waist: 75.75um : 20.02.17
  • Waist measurement: Lattice: 66.88um +/- 4.4

Reducing the linewidth: Measurements:
