Experimental study of ultracold cesium atom photoassociation spectrum using an amplitude modulation technique;

Through the balance probe for polarization spectrum of cesium atoms,when the angle of the transmission axis of the polarization spectrum tilted with respect to the polarization axis of polarization beam splitter(PBS) is appropriate,then the achieved signal is just the dispersion frequency discrimination error signal of cesium .

We report the basic idea and experimental demonstration of measuring the temperature of cold cesium atomic cloud confined in a magneto-optical trap (MOT) by analyzing absorption spectrum observed in the short-distance time-of-flight (TOF) method.

The temperature of cold cesium atoms loaded into the lattice is measured via the short-distance time of flight(TOF) absorption spectrum.

Utilizing a focused weak continuous-wave laser beam,the cold cesium atoms,which are cooled and trapped from the slow tail of cesium vapor at room temperature,are continuously transferred from vapor-cell MOT to UHV MOT.

The capacitance variation is proportional to the number density of Cs atoms.

It is expounded that a Cs atom may have large permanent electric dipole moment.
