• 論文の詳細を見る

• The velocity of a cesium atomic beam was controlled using two broadband frequency-modulated, external-cavity diode lasers. One laser beam was used to decelerate faster atoms and the other was used to accelerate slower atoms. The central velocity of the atoms was readily tuned in a wide range while maintaining the width and peak height of a velocity distribution. In addition, the velocity distribution of cesium atoms was calculated on the basis of the scattering force caused by two frequency-modulated laser beams. The calculated peak ratio was in good agreement with the experimental result.
