| 摘 要： | 在统一展开理论的框架内，通过提高推导过程中的精度，得到了更精确的结果，且将其推广应用到激光系统中。具体研究两个激光模型，得到了它们的光强定态几率分布、光强平均值及相相对涨落，通过比较发现，本文所得到的结果明显的改善了用统一色噪声的似所得到的结果而与精确的数值结果和数值模拟结果符合更好。

| Abstract: | In the frame of the unified expansion theory(UET) we obtain the higherprecision expressions of the UET by means of improving the accuracy of calculation,andthen extend it to the laser systems.Two single-mode dye-laser models are studied by themodified UET, and the expressions of stationary probabilities, means and variances laserintensity are obtained. Comparison shows that the results of the modified UET agree wellwith the exact numerical results and the simulation results better than the results of theunified colored-noise appreximation (UCNA). |
