摘要
本文运用约束型折叠腔概念，通过数值计算，分析了第２类新光束的模式分布与输出特性，得到了一束近场为准基模（光模），远场为环模的第２类新光束。理论分析与实验结果相吻合。
A new method of confined and folded resonator was used to solve the problem of the mode distribution and output characteristics of the Second Kind of New Beam by numerical calculation.The second kind of beam was obtained which is quasi TEM 00 mode in the nearfield and quasi TEM 01 in the far field.The results are consistent with the experiment.
