Typical experiments employ beams of cold, slowly moving neutral atoms, as a special case of a particle beam. Like an optical beam, the atomic beam may exhibit diffraction and interference, and can be focused with a Fresnel zone plate [2] or a concave atomic mirror. [3] For comprehensive overviews of atom optics, see the 1994 review by Adams ...
Doppler cooling involves using laser light that is red-detuned from an atomic transition, which means the laser frequency is higher than the natural resonance frequency of the atoms. When atoms move towards the laser beam, they experience a higher frequency light shift, resulting in an optical force that slows them down.
Atomic beam is special case of particle beam; it is the collimated flux (beam) of neutral atoms. The imaging systems using the slow atomic beams can use the Fresnel zone plate (Fresnel diffraction lens) of a Fresnel diffraction mirror as focusing element. The imaging system with atomic beam could provide the sub-micrometre resolution.
The idea of the atomic fountain was first proposed in the 1950s by Jerrold Zacharias. [6] [7] Zacharias attempted to implement an atomic fountain using a thermal beam of atoms, under the assumption that the atoms at the low-velocity end of the Maxwell–Boltzmann distribution would be of sufficiently low energy to execute a reasonably sized parabolic trajectory. [8]
An atom interferometer uses the wave-like nature of atoms in order to produce interference. In atom interferometers, the roles of matter and light are reversed compared to the laser based interferometers, i.e. the beam splitter and mirrors are lasers while the source emits matter waves (the atoms) rather than light.
