摘要
本文研究了周期外力对单模激光增益模型所做的功,结果表明:功随周期外力角频率的变化出现一个极大值,即出现能量随机共振现象,并详细讨论了系统参数和噪声强度对共振峰的影响.
This paper studies the work which is done by periodical external force to the gain-noise model for a single-mode laser. Result shows that the work exhibits a maximum as the angular frequency of the periodical external force varies,and the energetic stochastic resonance occurs; and the influence of system parameter and noise intensity on the resonance peak is discussed in detail.
