采用衍射光学技术耦合叠加激光光束的研究

摘要

A new method of adding laser beams coherently has been proposed in the article.Numerical simulation of 1-dimension based on the Yang-Gu algorithm shows that the combination efficiency is greater than 98.9%,error less than 0.19% when the diffraction optical elementary(DOE)'s phase is 16-level quantized.Also error analysis has been done here.%文中提出一种用以实现激光光束耦合叠加的新方法。采用杨顾算法进行的1-维数值模拟结果表明，在衍射光学元件位相16阶量化的情况下，可以实现效率为98.9%，误差为0.19%。另外从进行的误差分析我们看到，只要衍射光学元件的最大蚀刻误差小于5%，则可以很好地实现激光束的耦合叠加。
