| Outline of Final Research Achievements |
In ulta-high field of focused laser beam vacuum breakdown is expected to happen theoretically but is hard to achieve experimentally. To approach such high fields, a relativistic flying mirror (RFM) was proposed. We have demonstrated some of the proof-of-principle of RFM. Within the scope of the current project we seek for the focusability improvements by RFM. We conducted RFM experiments and observed reflected light from the RFM at an extreme ultraviolet region. The source size of the RFM was smaller than 7.1 μm, which is approximately half of the previously measured value. In addition we have found a better spatial resolution method and shown that it is possible to measure with a resolution of 1μm. In order to improve stability, we tried to observe the RFM structure and have seen the RFM (actually nonlinear wake) with a short probe pulse.
