Outline of Final Research Achievements

When the ultra-short pulse high power laser is focused on MPa class high density gas, part of laser plasma electrons inside plasma is accelerated into a few 10 MeV. The authors get an idea to obtain the monochromatic and arbitrary energetic X-ray. If we inject the laser plasma electrons into the single crystal, such X-rays are generated by the interaction between the electrons and the electric field of crystal. This method is called parametric X-ray method. The pulse duration of the X-rays is less than 100 fs because of short pulse duration of laser plasma electrons.
In this study, the authors produced the laser plasma electrons and tried the parametric X-ray generation.
