摘要
大面积衍射光栅的研制一直是研究的重大课题之一,同时大面积衍射光栅的制作以及获取是光栅研制的一个技术难点,啁啾脉冲放大(CPA)技术的出现更加加剧了对米级光栅的需求。由于大口径光栅制造技术难实现和经济代价高昂的限制,因此采用拼接的方法增大光栅的尺寸成为公认的经济有效的途径。详细介绍了光栅拼接的理论研究,并在此理论指导下,重点介绍了光栅拼接的实验研究,这些研究包括拼接误差检测准直、拼接误差精密调整以及光栅稳定性控制研究。
Abstract
The manufacturing of large-scale diffraction gratings is always one of great tasks, and how to obtain meter-sized is also a very difficult problem. The appearance of the chirped-pulse amplification (CPA) promotes the need of gratings. Because of technological and financial limit, an alternative to mosaic two or more gratings into an equivalent single grating is proposed. Theoretical research of tiled-gratings is described, and experimental studies which include alignment errors test, accurate adjustment and stability control are also introduced.
