< About the research >

Our laboratory studies the development and application of photon and quantum beams. Although the name "photon and quantum beams" may not imagine well, our research targets light from lasers and quantum beams produced from accelerators. These technologies are widely used in society and are necessary for making the PCs/smartphones that you are looking at on this page.




These photon science and quantum beam science are closely related. The most advanced X-ray lasers are derived from electron beams from accelerator, and the acceleration gradient (energy per unit length) is being updated by laser-produced plasma acceleration. Our goal is to further develop the relationship between these two fields to form a fusion area. The fusion of technologies from both fields will greatly expand applications, such as the realization of “on-chip” ultra-compact accelerators (1), compact X-ray lasers, attosecond science, and novel photon and quantum beam sources.

In our laboratory, we design and fabricate/build lasers (2) and accelerators (3) for research by ourselves as much as possible. Our current research topics are, integrating photon and quantum beam technologies, as follows:

▷ Research on electron beam acceleration with an acceleration structure made by laser processing (1-3)

▷ Research on electron acceleration using laser beams generated by electron beams (4)


< Future Aspirations>

Our laboratory will promote research activities to form a fusion area between photon science and quantum beam science. We will pursue researches toward ambitious goals, aiming to create new value through technological fusion of photon and quantum beam.
