| 1 | Effects of second-order dispersion of ultrashort laser pulse on stimulated Raman scattering显示文摘The influence of second-order dispersion(SOD)on stimulated Raman scattering(SRS)in the interaction of an ultrashort intense laser with plasma was investigated.More significant backward SRS was observed with the increase of the absolute value of SOD(|ψ2|).The integrated intensity of the scattered light is positively correlated to the driver laser pulse duration.Accompanied by the side SRS,filaments with different angles along the laser propagation direction were observed in the transverse shadowgraph.A model incorporating Landau damping and above-threshold ionization was developed to explain the SOD-dependent angular distribution of the filaments. | Yanqing Deng Dongning Yue Mufei Luo Xu Zhao Yaojun Li Xulei Ge Feng Liu Suming Weng Min Chen Xiaohui Yuan Jie Zhang | 2022 | High Power Laser Science and Engineering2022，10，6： | 0 |
