摘　　要：对方形和圆形腔镜对称共焦腔的横向光场分布进行了仿真研究,能够模拟任意横模的横向光场分布,而且能够对不同横模混合后的横向光场分布和光腔中的行波场进行模拟,并绘出光强分布和振幅分布的二维或三维图形。编写了简明的用户界面,能够选择腔镜类型、光腔参数、仿真对象等,使激光器横向光场的仿真可视化、简单化,有助于学生理解和掌握激光器横模的光场分布规律。The mode-field distribution of symmetricconfocal resonator with round and quadrate mirrors is simulated. The field distribution of any single transverse modes, several transverse modes mixtures, and the traveling wave in resonator can be calculated. The field distribution patterns of optical amplitude and intensity are given in both 2-dimension and 3 dimension images. At the same time, the interface program is given, the type of resonator, the parameters of resonator, the item of simulation item etc. can be selected. The complicated, nonobjective mode-field distribution is visualized by the interface and simulation program, it is significant to help the students understand mode-field distribution of laser.
