研究了量子力学预测与经典计算结果不一致的非线性光学效应。某些初始条件，那些不稳定平衡或那些导致不稳定平衡的条件，经典地会引起辐射强度的非周期性。这种系统的一个例子是二次谐波产生，由于这种非周期性对实验观测的潜在的舒适性，所以对其进行了详细的研究。给出了二次谐波光强度和光子统计演化的数值和解析预测。预测二次谐波光的光子统计将在第一个强度极大值之后经历一个急剧的跃迁。
Nonlinear optical effects where quantum mechanical predictions are at variance with the results of classical calculations are studied. Certain initial conditions, those of unstable equilibrium or those that lead to unstable equilibrium, classically, give rise to an aperiodicity in the intensity of the emitted radiation. One example of such a system is second-harmonic generation, which is studied in detail because of the potential amenability of the aperiodicity to experimental observation. Numerical and analytic predictions for the evolution of the intensity and photon statistics of the second harmonic light are presented. The photon statistics of the second harmonic light are predicted to undergo a sharp transition following the first maximum of the intensity.
