Abstract

A simple control method for the velocity distribution of cesium atoms is demonstrated using a frequency modulated diode laser with a wider spectrum. Current to the diode laser was modulated and the laser spectrum was broadened to overlap the Doppler broadening of the atomic beam. The reduction of the atom velocity was achieved on the basis of the laser cooling technique and a single narrow peak at approximately 45 m/s was observed. From a view point of a novel purification process, the possibility to deflect this cooled cesium atomic beam was discussed to spatially separate the beam from impurities.
