摘要
提出了利用时间延迟反馈控制的方法来抑制单模激光系统的涨落。通过小时间延迟近似,导出了单模激光场的定态几率分布函数的解析表达式,计算了激光强度的平均值、归一化方差和偏度系数。结果发现,时间延迟反馈控制能很好的抑制激光系统的涨落。同时利用Matlab进行了相应的数值计算模拟。结果显示,数值模拟的结论与解析解符合得很好。
A control mechanism of time-delayed feedback is designed to suppress the fluctuation of a sin- gle-mode laser. Using the small time delay approximation, the analytic expression of the stationary probability distri- bution function of the single-mode laser filed is obtained. The mean, normalized variance and skewness of the steady-state laser intensity are calculated. It is found that the time-delayed feedback control can suppress the inten- sity fluctuation of the laser system. Matlab is used to perform numerical simulation and the results accord with the approximate analytic results.
