从量子统计的角度描述了光与物质的非线性相互作用。讨论了双光子吸收、拉曼跃迁、和频产生、参量放大和非相干散射等情况。结果表明，非线性光学效应在很大程度上取决于光场的统计特性。非线性吸收、产生和放大的速率，混沌比相干高，多模也比单模泵浦场高。对输出字段的统计量的测量可以产生关于输入字段的统计量和介质的属性的信息。
Nonlinear interaction of light with matter is described from the quantum-statistical point of view. The cases of two-photon absorption, Raman transition, sum-frequency generation, parametric amplification, and incoherent scattering are discussed. It is shown that the nonlinear optical effects depend strongly on the statistical properties of the light fields. The rate of nonlinear absorption, generation, and amplification is higher for chaotic than for coherent, and also higher for multimode than for single-mode pump fields. Measurements of the statistics of the output fields may yield information about the statistics of the input fields and the properties of the medium.
