应用一般形式的统一色噪声近似得到了染料激光色立方模型光强分布的福克－普朗克方程。导出了光强分布函数，描述了光强涨落的实验和数值模拟结果以及色泵噪声对光强涨落的影响。 The Foucault - Planck equation of intensity distribution of the dye laser color cube model is obtained by the general form of uniform color noise approximation. The light intensity distribution function is derived. The experimental results of numerical simulation of light intensity fluctuation and the effect of color pump noise on the light intensity fluctuation are described.
