Abstract

我们导出方程并且学习二光子的激光,在洞的电磁的地被协调地准备的三水平的原子和古典地在驾驶注入了洞的串联的非线性的动力学。如此的一个系统的动态方程被使用量 Langevin 操作员的技术导出,然后在不同开车条件下面数字地被学习。结果在某些条件下面显示出那二光子的激光能产生的串联混乱,加倍的时期,周期、稳定、双稳态的状态。混乱能被原子人口,原子连贯,和注射的古典地禁止。另外,没有混乱发生在光双性人稳定性。

Dynamic Equations and Nonlinear Dynamics of Cascade Two-Photon Laser

Xie Xia, Huang Hong-Bin, Qian Feng +3 more

We derive equations and study nonlinear dynamics of cascade two-photon laser, in which the electromagnetic field in the cavity is driven by coherently prepared three-level atoms and classical field injected into the cavity. The dynamic equations of such a system are derived by using the technique of quantum Langevin operators, and then are studied numerically under different driving conditions. The results show that under certain conditions the cascade two-photon laser can generate chaotic, period doubling, periodic, stable and bistable states. Chaos can be inhibited by atomic populations, atomic coherences, and injected classical field. In addition, no chaos occurs in optical bistability.

Effects of Atomic Coherence and Injected Classical Field on Chaotic Dynamics of Non-degenerate Cascade Two-Photon Lasers

Yajun Zhang, Huang Hong-Bin, Peng Yang +1 more

Based on the cascade two-photon laser dynamic equation derived with the technique of quantum Langevin operators with the considerations of coherently prepared three-level atoms and the classical field injected into the cavity, we numerically study the effects of atomic coherence and classical field on the chaotic dynamics of a two-photon laser. Lyapunov exponent and bifurcation diagram calculations show that the Lorenz chaos and hyperchaos can be induced or inhibited by the atomic coherence and the classical field via crisis or Hopf bifurcations.
