Abstract
This paper presents the results of experimental and theoretical investigations on the control of atomic beam motion by light pressure of laser radiation. Collimation, focusing, and compression of an atomic beam are considered. Collimation of an atomic beam was achieved under the interaction of laser radiation with atoms when the light pressure force depended only on the atoms’ velocity. A similar regime of atomic beam interaction with radiation was performed under transversal irradiation of a beam by the axisymmetric field. The latter was formed by laser radiation reflected from the conical mirror surface of a reflecting axicon. The axis of an atomic beam coincided with that of the axicon. The collimation regime was reached under negative detuning of the laser radiation frequency from that of the atomic transition one by a value equal to a few homogeneous widths. Under positive detuning by the same value beam decollimation was observed.
