For example, the solution of the problem of laser cooling and trapping of atoms has given birth to the new field of the physics of ultracold matter, i.e. quantum atomic and molecular gases. The laser non-coherent control of uni-molecular processes has found an interesting extension in the field of laser coherent control of molecules.

Laser Cooling and Trapping of Neutral Atoms

Our group discovered that sodium atoms could be laser cooled well below the lower limit the Doppler limit predicted by the then generally accepted theory. Two main consequences of that discovery were a revamping of the theory of laser cooling and a renewed interest in the applications of laser cooling because of the far lower temperatures. Both of these effects are …

May 23, 2019· Abstract. By shining laser light onto an assembly of neutral atoms or ions, it is possible to cool and trap these particles. We study a simple cooling mechanism, Doppler cooling, and we derive the corresponding equilibrium temperature. Then, we show that the cooled atoms can be confined in the potential well created by a focused laser beam.

We find efficient sub-Doppler cooling in our trap, which can persist even in large magnetic fields due to the near degeneracy of two Lande g factors. Furthermore, a continuously loaded magnetic trap is demonstrated where we observe temperatures below 25 υK.
