Laser intensity induced transparency in atom
... 3 Cesium atom-molecule system case In order to demonstrate the laser intensity induced transparency, a specific frequency was chosen, at which the PA laser intensity was set to 300 W/cm2, such that the resonant frequency is not influenced by the variation of PA laser intensity. The binding energy of ...

Manipulating Atoms with Photons
... A first interesting feature of these optical methods is that they provide a very efficient scheme for polarizing atoms at room temperature and in a low magnetic field. Secondly, they have a very high sensitivity. A single RF transition between the 2 ground state sublevels is detected by the subseque ...
