| 摘 要： | 数值分析了调制泵浦作用下的二次谐波产生系统的浑沌动力学行为.考虑到混沌运动的遍历性,提出一种研究浑沌态光场光子统计的数值方法,即通过数值积分求解系统动力学方程估计光子数的系统平均.运用这一方法于二次谐波系统,计算了其在浑沌态下的光子统计分布,结果表明是一种超Poisson分布.

| Abstract: | Chaotic dynamics in the second-harmonic generation driven by a pump modulated with frequency is numerically investigated. In consideration of ergodicity of chaos,a numerical method for the study of photon statistics of chaotic light field is presented, in which the ensemble average of photon number is estimated by numerically integrating the dynamical equations of the system. It is applied to the second-harmonic generation and super-Poisson photon statistics is found when the system is in chaotic state. |
