该技术使探测器工作在更加安全高效的模式下，最后实验测得探测器总的死时间由原全被动模式下大于2us缩短至120ns，单光子计数率由被动中低于1MHz上升到8MHz以上，因此可以满足一些高速光子计数的需要。

The entangled properties of motorial atom and field in the two-photon Jaynes-Cummings model with atomic motion are studied by using the quantum information theory.

We establish the quantum theory of the one-mode micromaser injected by ultracold V-type three-level atoms with atomic coherence, and discuss the properties of the emission probability, the photon statistics, the spectrum and the velocity selection. We find the following results. There are two sets of peaks in the plot of the emission probability versus the cavity length. The injected atomic coherence can deeply affect the values of the two sets of peaks and the unresonant platform.
