连续染料激光中的有色噪声

COLORED NOISE IN A CW DYE LASER

我们分析了连续染料激光在定态工作时有色倍增噪声对激光输出的影响。用Hanggi分解因子来近似有色倍增噪声,通过福克——普朗克方程求出了激光强度的平均值、方差和偏斜度的解析解。同实验数据相比较,理论值和实验值符合得很好。

The effect of colored multiplicative noise on the laser output for a cwdye laser at steady state is analysed by means of the Hanggi's ansatz. Analytic solutions of the mean, variance and skewness of the laser intensity are calculated through a Fokker-Planck equation. Compared with experimental results, good agreement between theory and experiment is obtained.
