The beam division method in maskless laser interference photolithography can be divided into wave-front division and amplitude division. 摘要无掩模激光干涉光刻中的分束方法一般有波前分割和振幅分割。
The results show that the second Born approximation can succeed in bichromatic laser fields compared with the results of the First Born approximation. 结果表明,二阶玻恩近似理论在多模激光场中的应用也是比较成功的。
