Question

急求激光类英译中翻译，多谢啦！感激不尽~~~~~~

We have demonstrated an approach to the fast generation of diffractive laser beam shapers.A straightforward design procedure for PHOEs for radially symmetric or separable beam shaping problems was proposed.The limitations of the proposed algorithm and its suitability to several problems were confirmed in simulations,which resulted in diffraction efficiencies of 99.6%.The experimental realization of PHOEs in an azobenzene polymer was presented.The influence of typical fabrication errors that affect the achieved retardance in the polymer layer was explained.The experimentally achieved diffraction efficiency was approximately 79%,which is a value in the range of values achieved by other state-of-the-art DOEs.Separable intensity distributions and distributions with homogeneously illuminated areas can be fabricated too.Summarizing the results,we have demonstrated the application of PHOEs as potentially low-cost laser beam shapers with high efficiency.Because of the direct writing process,they can be adapted to the specific application with little effort and without the need for expensive lithography masks.A potential application of the demonstrated beam shapers might be rapid prototyping of beam shaping elements.To improve the quality of the generated PHOEs,it is nevertheless still necessary to improve the setup for the writing process and the quality of the azobenzene polymer thin films further.

我们已经证明一种方法的快速生成的激光衍射品牌。一个简单的设计程序PHOEs为径向非对称或分割提出了梁形成的问题。该算法的局限性和它的适用性几个问题被证实模拟,导致99.6%的衍射效率。实验实现PHOEs在一个液晶聚合物算法。典型的加工误差的影响,影响达到抗在聚合物层解释。实验获得的衍射效率约为79%,这是一个值在不同的值达到其他先进的做。可光强分布和分布与均匀照亮区域也可以编造。结果进行总结,我们已经证明PHOEs的应用可能会成为廉价的雷射光束品牌效率高。由于直接写作的过程中,他们能适应的具体应用和小的努力,也不需要昂贵的光刻面具。一个潜在的应用证明梁可能快速成型品牌塑造的梁元素。以完善的质量PHOEs生成的,不过还需要提高安装了写作过程和质量的液晶聚合物薄膜进一步.
