Photonics technology utilizing laser beams is essential not only for fundamental technology in various research fields but also for advancing scientific research. We focus on developing novel optics and photonics technologies for advanced laser sources and controlling light waves, targeting to expand into new materials science involving the interaction between light and matter. We are interested in controlling the spatial and temporal “structure” of light, such as amplitude, phase, polarization, and even temporal waveforms, which can create novel light properties applicable to various research fields. The present research topics include rapid three-dimensional or super-resolution imaging using structured light, laser nano-processing by femtosecond laser, and the wavefront control of an electron beam by the interaction of light and electrons.
