AC Stark effect of dipole trap and lattice. A typical fluorescence trace with lattice and dipole trap beam. During the MOT phase one atom is captured. Switching on the dipole trap reduces the fluorescence level by about 70%. In combination with the lattice a slight increase is observed because it compensates the light shift of the dipole trap. For the combination of MOT and lattice an increase of about 10% in fluorescence level is observed. In the end the count rate due to stray light and the dark count rate is detected. A binning time of 100 ms is used.
