| 摘 要： | 分别在好腔和坏腔两种典型的谐波转换条件下,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.运用文献1给出的方法,在新的条件下研究了系统在浑沌态下的光子统计,结果表明仍为超Poisson分布,而且在某些情况下,浑沌态光场的光子数相对涨落甚至比热光场的光子数相对涨落还要大.最后得出了普遍性的结论;二次谐波系统在浑沌态下的光子统计为形式丰富多样的超Poisson分布,浑沌光场是一种强度高、涨落大的光场.

| Abstract: | Chaotic dynamics in the second-harmonic generation driven by a pump modulated with frequency is numerically investigated in the cases of good frequency conversion limit and bad frequency conversion limit respectively. Photon statistics of the system when it is in chaOtic state is studied by the methOd presented in our previous paper1. Super-Poisson photon statistics is fOund here as in paper1] and the relative fluctuation of photon number of chaOtic light field can be even larger than that of thermal light field in some cases. Finally,we come to the conclusion that photon statistics of chaotic light field in second-harmonic generation is super-Poisson distribution of various forms and the chaotic light field is of high intensity and large fluctuation. |
