| 摘 要： | 在理论上建立起将受激布里渊散射（SBS）与激光大气传输过程相结合的激光补偿传输的数学模型,并进行了数值模拟，提出并证明了利用SBS阈值效应可以将相位共轭光会聚到目标上一个小面积上，从而在目标上主动获得小面积信标光斑。利用SBS实现激光大气补偿传输（传输距离250m）的实验研究,证实了上述理论预期。

| Abstract: | A mathematical model of laser compensation propagation process by combining the stimulated Brillouin scattering (SBS) and laser propagation in the atmosphere is constructed and the numerical simulation is also conducted. On the basis of realizing a beacon of a small area on an uncooperative and extensive target with SBS threshold, we presented and demonstrated the feasibility of the method to actively obtain the phase conjugate light on the target. The experiments of laser propagation with SBS are conducted in case of a 250m distance, which shows that by utilizing the SBS threshold effect the small area beacon could be obtained on the target actively. |
