Atomic fountain apparatus

摘要

An atomic fountain apparatus laser trapping, cooling and tossing upward atoms with a plurality of laser beams comprises a collimation laser generating section and a microwave resonator, The atoms fall back through a microwave resonator are observed. The collimation laser generating section generates a laser beam of a frequency that does not resonate with the atoms. The collimation laser beam output by the collimation laser generating section is applied to the atoms in the direction of the tossed atoms, and the switch is turned off before the atoms reaches the microwave resonator. <IMAGE>
