Abstract: Sodium laser beacon (SLB) excited by a macro-micro pulse laser with low power has the following advantages: the return photons without fluctuations and the high merit quantity, although the laser beam propagation and the size of SLB suffer form the atmospheric turbulence. In addition, the macro-pulse profile may influence the interaction of laser and sodium atoms. For the macro-pulse with a Gaussian profile, it is useful to enhance the merit quantity and the excitation probability of the SLB to increase the width of micropulse. In order to obtain more of the return photons in the SLB, while increasing the laser power, the fine beam quality, the appropriate launch diameter, and the spectral width of the laser etc. must be considered. Therefore, it is of practical significance for the SLB with fine characteristics to optimize the laser parameters, the launch diameter and launch pattern.
