Abstract
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.

Atomic fountain apparatus trapping, cooling and tossing upward atoms with a plurality of laser beams comprising:
- a collimation laser generating section for generating laser beam of a frequency that does not resonate with the atoms,
- wherein the collimation laser beam output by the collimation laser generating section is applied to the atoms in the direction of the tossed atoms to collimate the tossed atoms.
An atomic fountain apparatus trapping, cooling and tossing upward atoms with a plurality of laser beams, and comprising a microwave resonator, wherein the atoms pass upward fall back through a microwave resonator comprising:
- a collimation laser generating section for generating laser beam of a frequency that does not resonate with the atoms;
- and
- a switch for controlling on and off of the light output from the collimation laser generating section;
- wherein 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.
