中文摘要:
采用长焦距透镜与连续介质气体靶是目前高亮度高次谐波产生实验中谐波产率较高的方案,在长焦距透镜方案中进一步探索使用准相位匹配技术,有望在连续介质靶的基础上进一步提高高次谐波信号的强度。根据准相位匹配技术,设计了一种多喷嘴阵列气体靶,通过模拟计算的方法,对比传统连续介质气体靶与多喷嘴气体靶这两种方案,从理论上证实多喷嘴气体靶可以实现谐波信号强度的进一步提升。

英文摘要:
Combining a long-focus lens with a continuous medium gas target is a scheme with high conversion efficiency in high-order harmonic generation.The quasi-phase matching technique is applied to this scheme.It is expected to further improve high-order harmonic signal intensity.A multi-jet arrays gas target is applied to the generation of high-order harmonic,which is designed according to the quasi-phase matching technique.It is theoretically confirmed by numerical simulation that the multi-jet arrays gas target could improve the harmonic signal intensity compared with traditional continuous medium gas target.
