In vivo optical imaging and optical manipulation by using a novel
multiphoton microscopy with advanced ultrashort light pulses and their application for cancer research and medicine

Takeshi Imamura ProfessorTakeshi Imamura
Ehime University, Professor

Website of the Lab

In order to establish an innovative “in vivo” optical imaging, we will develop a novel non-linear optical microscopy by combining with adaptive optics and advanced light sources including an optical parametric oscillator, a supercontinuum light source and a small size femtosecond mode-locked laser source. The multiphoton microscopy will enable real-time image of multiple events in cancer cells and their microenvironment, and our research will facilitate development of novel light sources.

Development of the frontier of nonequilibrium materials leaded by optical science

Shin-ya Koshihara ProfessorShin-ya Koshihara
Tokyo Institute of Technology, Professor
Website of the lab

Development of techniques for probing the lattice-electronic combined structural dynamics in nano-scale is essential to open new frontier of materials science. These technologies will realize new class of materials which shows highly sensitive photo-induced phase switching. Especially, dynamical X-ray structural science combined with domain observation by time-resolved PEEM will be powerful tool for promoting this new research field. We develop new light source for these probing technologies and an appearance of new field of materials science which can be named as 'nonequilibrium material science under critical condition', beyond the hitherto structural science.

Toward the realization of monocycle entangled photons for novel nonlinear quantum optics

Shigeki Takeuchi ProfessorShigeki Takeuchi
Hokkaido University, Professor
Website of the lab

Photons entangled on timescales of one period of the light field oscillation represent the ultimate limit of quantum correlations in time and frequency. In this project, we aim to generate such monocycle entangled photons by developing sophisticated quasi-phase-matched nonlinear optical devices. This optimization of the spectral and temporal features of light enables us to explore new aspects of optical nonlinearities at the quantum level, e.g. enhanced two photon absorption and related non-linear two photon interactions, or ultra-sensitive measurements in quantum metrology.

Advanced Terahertz Spectroscopy with High-power Terahertz Light Source and its Application to Materials Science

Koichiro Tanaka ProfessorKoichiro Tanaka
Kyoto University, Professor
Website of the lab

We will develop a tunable high-power terahertz light source whose peak electric field is comparable to that inside the active semiconductor device and try to establish a novel non-linear terahertz spectroscopy for solid, liquid, and biological materials. We will visualize terahertz coherent transients in mesoscopic structures with real-time near-field terahertz microscope and semiconductor quantum structures using high-power terahertz light source. These advanced terahertz technologies will open new aspects in solid state physics such as nonperturbative nonlinear optical processes.

Development of ultrafast atomic-scale imaging device using laser-plasma-driven single electron bunch

Tomonao Hosokai Specially-appointed Associate ProfessorTomonao Hosokai
Osaka University, Specially-appointed Associate Professor

We are going to develop a single-shot electron imaging device with the femtosecond temporal and the atomic-scale spatial resolutions, which enables us to observe ultra-fast transient phenomena in condensed matter.
In order to establish a high-performance ultra-short-pulse electron source for the imaging device, we shall elaborate a laser-plasma-driven electron injector, called the Laser Virtual Cathode (LVC) and based on the laser plasma electron acceleration, as well as the photo-controlled RF cavity techniques. In addition, we will expand the pulsed-power-driven electro-magnetic optics as the key component of the imaging system, which must be synchronized with the laser-driven electron pulses from the LVC.
