摘　　要：基于虚、实部互关联的量子噪声及泵噪声驱动的单模激光模型的Fokker Planck方程,运用平均弛豫近似方法研究了该激光模型的动力学性质。计算了光强关联函数以及相应的平均弛豫时间,讨论了量子噪声实虚部的互关联强度对光强关联函数以及弛豫时间的影响。结果表明,在阈值以上量子噪声实、虚部关联的存在总是使得光强涨落的弛豫变缓。Based on the Fokker-Planck description of a single-mode laser model with correlations between the real and imaginary parts of the quantum noise as well as the pump noise,the dynamical properties of the laser system were studied by using of the mean relaxation time approximation method.The intensity correlation function and the associated mean relaxation time were calculated.It is found that the presence of correlations between the real and imaginary parts of the quantum noise always slows down the relaxation of the light intensity fluctuation when the laser is operated over the threshold.
