| Research Abstract |
We investigated the fast ignition with self-guiding of ultra-intense laser pulse via relativistic self-focusing effect. In this research, we demonstrated the possibility of stable propagation of laser pulse by choosing an optimum focusing position, and narrowing of electron emission angle under self-focusing. We also propose a new heating mechanism of fast electrons against the core plasma from the measurement of electron energy spectrum. These achievements could exhibit the possibilities of efficient heating and ignition of the fuel under this scheme.
