对于考虑后脉冲效应的大范围输入光功率，我们推导出了单光子探测器计数概率的解析表达式。通过用连续激光照射饱和商用单光子探测器获得的数据进行拟合，证实了该表达式的有效性。从FITS中提取的探测器效率和后脉冲概率符合低重复频率的制造规范。
We derive an analytical expression for the count probability of a single photon detector for a wide range of input optical power that includes afterpulsing effects. We confirm the validity of the expression by fitting it to the data obtained from a saturated commercial Single Photon Detector by illuminating it with a cw laser. Detector efficiency and afterpulsing probability extracted from the fits agree with the manufacture specs for low repetition frequencies.
