我们证明了实验控制的时间尺度上的混沌系统比以往任何研究都要短得多。将多段激光器与外部法布里-珀罗标准具相结合，混沌输出转换为频率在10 GHz范围内的规则强度自脉动。控制是无创的，因为当达到目标状态时，来自标准具的反馈是最小的。光学相位被确定为一个关键的控制参数。数值模拟与实验数据吻合良好，揭示了全局控制特性。
We demonstrate experimentally control of a chaotic system on time scales much shorter than in any previous study. Combining a multisection laser with an external Fabry-Perot etalon, the chaotic output transforms into a regular intensity self-pulsation with a frequency in the 10-GHz range. The control is noninvasive as the feedback from the etalon is minimum when the target state is reached. The optical phase is identified as a crucial control parameter. Numerical simulations agree well with the experimental data and uncover global control properties.
