Apparatus for atomic clock comprising :
- first and second distinctive substrates (1,2), each having at least a planar surface (10, 20) substantially parallel therebetween;
- a medium (3) having particles capable of undergoing energetic transition between at least two energy levels, said medium (3) being located in the space defined between said planar surfaces (10, 20);
- a magnetic device (4) arranged to the first substrate (1) and generating at least in the volume of the medium (3) a predetermined static magnetic field B the direction of which is substantially parallel or perpendicular to the planar surfaces (10, 20);
- an excitation (5) device arranged to the second substrate (2) and generating an excitation magnetic field H at, at least an excitation frequency, the direction of said excitation magnetic field H in the volume of the medium being substantially orthogonal to said direction of the static magnetic field B . |
