Manipulation of Atoms by Laser Light

Wolfgang A. Ertmer

Laser cooling and laser manipulation of free neutral atoms have reached a level of sophistication not foreseen just a few years ago. This concerns trapping of neutral atoms at μK temperatures as well as the precise preparation of extreme dense and ultra cold atomic beams. These techniques offer plenty of new experiments answering basic physical questions or allowing totally new levels of precision. The following article will explain, how to prepare such cold beams and it will demonstrate the resulting possibilities for a Ramsey spectrometer at the intercombination line of magnesium. Furthermore first results with this spectrometer set up as magnesium atom interferometer will be presented.

Effect of a Sinusoidal Excitation Amplitude on the Performance of an Atomic-Beam Spectrometer

J.H. Shirley

A theoretical analysis has been made of the transition probabilities for a Rabi-type atomic-beam spectrometer in which the exciting field amplitude seen by the atoms has a sinusoidal rather than a rectangular envelope. The time-dependent Schr\"odinger equation was integrated numerically and a velocity average of the transition probabilities performed. The results indicate that the linewidth increases as the fourth root of the excitation power and that frequency shifts due to coupling of the exciting field with other atomic states are reduced by an order of magnitude at excitation powers much above optimum.

Atomic Beam E-H Gradient Spectrometer

Benjamin B. Bederson, Josef Eisinger, Kenneth H. Rubin +1 more

A novel atomic beam magnetic substate selector is described. A potential difference is applied to the insulated pole faces of an inhomogeneous magnet. The resulting E and H fields are then approximately congruent throughout the gap region. A beam atom experiences forces due to its effective magnetic moment and induced electric moment which can be made to balance for particular magnetic substates, independent of the atomic velocity. State-selected beams of reasonable intensity and purity can thus be obtained.
