基于迭加原理 ,引入了利用双曲余弦 -高斯光束的相干迭加而得的新光束 ,结果表明这类迭加光场的场强分布在适当参数条件下可具有平顶结构 ,并且分析了这类迭加所得的平顶光束的束传播因子与束参数的关系。
Based on the principle of superposition, a new light beam which is obtained by the coherent addition of hyperbolic cosine-Gaussian beams is introduced. The results show that the field intensity distribution of this type of superposition field can have a flat top structure under appropriate parameters, The relationship between beam propagation factors and beam parameters of such superpositioned flattened beams.
