| Outline of Final Research Achievements |
In this study, we experimentally verified that the functions of "generation / acceleration" and "induction" of electrons by the interaction of intense femtosecond laser with a solid (plasma) target can be separated and controlled. That is, it was experimentally observed that an electromagnetic wave induced by a huge current generated by high-intensity laser solid interaction is converted and transferred as a surface electromagnetic wave on a metal surface placed in the vicinity. This strong surface wave has potential applications of fast deflection electron-optics and terahertz wave sources.
Also, based on our developed technologies of the ultrafast electron diffraction instrument using laser accelerated electrons, we have successfully observed the ultrafast phenomena of laser ablation by the laser accelerated short electron pulses. As a derivative of these studies, we have succeeded in capturing the laser pulse being focused and propagating in vacuum for the first time in the world.
