Correlation photon counting experiment under conditions of extreme photon flux

Popis výsledku v původním jazyce

The standard way to realize single photon counting experiment under conditions of extreme photon flux - order of 109 photons per second - is to minimize the detector dead time. In case of some correlation experiments when the goal is not to detect each photon but to measure photon statistics (like second order correlation function) some another approaches can be applied. We are presenting the one of them - synchronously gated detectors. The numerical estimations based on experimental data will be presented for several values of detector dead time and gate width. And it will be compared with using of non-gated single photon detectors from point of view of amount of data to process, data yield, and probability to detect correlation.
