摘要 本文利用最近所发展的产生函数(Generating Function)理论方法,研究了泵浦和探测场共同驱动下单分子二能级体系发射荧光光子的统计性质.给出了泵浦探测场对体系发射光子线型、MandelQ参数以及光子发射几率等统计量的影响.理论计算的单分子发射平均光子数与已有实验结果符合得很好. 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.
