Lailin Ji,Xiaohui Zhao,Dong Liu,Yanqi Gao,Cui Yong,Rao Daxing,Wei Feng,Fujian Li,Haitao Shi,Jiani Liu,Li Xiaoli,Lan Xia,Tao Wang,Jia Liu,Du Pengyuan,Xun Sun,Weixin Ma,Zhan Sui,Xianfeng Chen +18 more
TL;DR: It is found that the second-harmonic spectrum distribution is proportional to the self-convolution of that of a fundamental wave, and this research opens the door for the study of low-coherent nonlinear optical processes.
Investigation of phase effects of coherent beam combining for large-aperture ultrashort ultrahigh intensity laser systems.
Zexi Zhao,Yanqi Gao,Cui Yong,Zhongyang Xu,Ning An,Dong Liu,Tao Wang,Rao Daxing,Ming Chen,Wei Feng,Lailin Ji,Zhaodong Cao,Yang Xuedong,Weixin Ma +13 more
TL;DR: In this article, the phase effects of coherent beam combining for large-aperture ultrashort laser systems are investigated theoretically and a series of numerical simulations are presented to obtain the requirements of spatial phase for specific goals.
