泵浦探测场下单分子体系荧光光子的统计性质

Abstract

The statistical properties of fluorescence photon emission of single molecule modeled by two-level system (TLS) under pump-probe fields were investigated by employing the generating function method developed recently. We study the impact of pump-probe fields on some single molecule statistical properties, such as, the line shapes, Mandel Q parameters and probalities of photon emission. Our theoretical result about average emission photon numbers and experimental result are in good agreement.
