In order to reduce the dead time and enhance the counting rate of single photon avalanche detector with higher quantum efficiency , we design a flexible and chronometrical circuit which realizes the excellent active technology with active quenching and fast reset.

該技術(shù)使探測器工作在更加安全高效的模式下，最后實驗測得探測器總的死時間由原全被動模式下大于2us縮短至120nsh高潮娇喘抽搐动漫视频，單光子計數(shù)率由被動中低于1MHz上升到8MHz以上国产3p视频，因此可以滿足一些高速光子計數(shù)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.
