摘要
设计了用于将HeNe激光基模光束整形为环形光强分布的光束二元光学元件;并进行了实验分析,在实验中,主要改变输出面距BOE的距离L,测得输出面的衍射效率,并与数值计算相比对。
A binary optical element which is designed to convert a single mode He Ne laser beam into a ring shaped intensity distribution is investigated experimentally. The measured diffraction efficiency are compared with numerical calculation when the distance between BOE and the output plane is changed.
