英文摘要：

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.
