| 摘 要： | 采用周期信号调制色泵噪音驱动的单模激光模型,运用线性化近似方法研究了单模激光系统光强关联函数C(t)随时间的演化关系,分析了调制信号的振幅B、频率Ω等对光强关联函数随时间演化的影响.发现在泵噪音自关联时间τ<<1的情形下,随着调制信号频率Ω、振幅B的增加,C(t)随时间的演化为单调衰减;在τ>>1的情形下,随着调制信号频率Ω、振幅B的增加,C(t)随时间的演化均为周期性振荡衰减.

| Abstract: | Using the linear approximation method, the intensity correlation function C(t) of a single mode laser system was calculated and the time evolution of C(t) was researched as well as the influence of modulation signal frequency Ω and amplitude B on C(t) was analysed in detail. In the case of the pump noise self correlation time τ>1, as modulation signal frequency Ω and amplitude B increasing, the time evolution of C(t) exhibits periodically surging with descending envelope. |
