Abstract
There are two methods to produce cold atomic beam. One is to use effusive thermal atomic beam, which is decelerated by the force of a counterpropagating laser. The other is to use trapped atoms, which are ejected from magneto-optical trap. Recently, it is reported that an atomic beam has been produced using the second method.1 We also have produced pulsed cold atomic beam from an axicon trap. It is the simplest setup that employs only a single laser beam to trap the atoms in axicon.2
