Third-Order Cross-Correlation Function of a Signal of Optical Free Induction and Stochastic Excitation

摘要

Excitation of a signal of optical free induction in an inhomogeneously broadened two-level system by a noise incoherent optical pulse whose length is comparable with relaxation times is considered. The third-order cross-correlation function of the system response and stochastic excitation is determined and its properties are studied.
