摘要
为了给出TEM11模式厄米-高斯光束的单光子捕获概率密度及概率，采用TEM11模式厄米-高斯光束激光脉冲作为单光子源，单光子捕获采用前驱波参考脉冲设置时间窗口的方法，对低轨道星-地链路中TEM11模式厄米-高斯光束单光子捕获概率进行了仿真分析，并给出了单光子捕获概率密度的分布和其最大概率．
The expressions of single-photon acquisition probability are deduced from TEM11 mode Hermite- Ganssian beams. Single-photon acquisition is analyzed for the links between a ground station and a satellite in a low earth orbit by means of using TEM11 Hermite-Ganssian beams as single-photon sources and a bright precursor reference pulse can be used to set a short time window.
