The characteristics of neutral Na atoms force is analyzed in laser Doppler cooling field.The characteristics of neutral Na atoms dissipative force is discussed based on Optical Bloch Equation and Density Matrix.The dissipative force′s characteristics is simulated under different laser cooling field parameters.The simulation results show that the lateral cooling can be realized by laser Doppler cooling field.It provides the important theoretical basis for the deposition atomic photoetching technology.

The forces acting on interacting moving atoms exposed to resonant laser radiation are calculated. It is shown that the forces acting on the atoms include the radiation pressure forces as well as the external and internal bias forces. The dependences of the forces on the atomic spacing, polarization, and laser radiation frequency are given. It is found that the internal bias force associated with the interaction of atomic dipoles via the reemitted field may play an important role in the dynamics of dense atomic ensembles in a light field. It is shown that optical size resonances appear in the system of interacting atoms at frequencies differing substantially from transition frequencies in the spectrum of atoms. It is noted that optical size resonances as well as the Doppler frequency shift in the spectrum of interacting atoms play a significant role in the processes of laser-radiation-controlled motion of the atoms.
