A6 Hidefumi AKIYAMA The Institute for Solid State Physics golgo アットマーク Advanced laser micro-spectroscopy is developed and applied to various semiconductor nano-structures, in order to understand and control their optical properties quantum mechanically which vary with their size and shape. Subjects are, for example, physics of short-pulse generation from semiconductor lasers, solar cells, firefly bio-luminescence, micro-spectroscopy and imaging with solid immersion lens, and time-resolved spectroscopy for characterization and development of novel samples. We have particular interests in finding and solving fundamental physics problems which limit semiconductor and optical technologies.
A6 Akira EJIRI Department of Complexity Science and Engineering Plasma is characterized by huge degree of freedom and strong interaction between particles or fluid elements. Plasma shows nonlinear response, an in a state far from equilibrium. In order to investigate the physics arising from these features, we put emphasis on fluctuations. Our main plasma device is the TST-2 spherical tokamak (Univ. Tokyo), and we operate it in cooperation with Prof. Takase's group. Typical plasma parameters are: major radius 0.38m, minor radius 0.25m, toroidal magnetic field 0.2 T, plasma current 100 kA. We also participate in experiments at LHD (NIFS) and JFT-2M (JAERI) devices.
A6 Takuro IDEGUCHI Institute for Photon Science and Technology We study optical science with advanced lasers. Currently, we are focusing on developing ultrafast spectroscopy and microscopy based on ultrashort pulse lasers including optical frequency combs. These techniques are to be powerful tools not only for physics but also for chemistry, biology, medicine, pharmacy and material science. Moreover, we aim at creating interdisciplinary or multidisciplinary science by combining optics with nanotechnology or microfluidics.
A6 Jiro ITATANI The Institute for Solid State Physics Our main research subjects are the development of advanced intense ultrashort-pulse lasers and their applications to attosecond sciences. We especially work on (i) the development of waveform-controlled intense light sources, (ii) generation of attosecond soft-X-ray pulses, (iii) coherent control of ultrafast processes in a strong laser field, and (iv) ultrafast soft-x-ray spectroscopy on femtosecond to attosecond time scales.
A6 Kuniaki KONISHI Institute for Photon Science and Technology We are searching for new physical phenomena caused by the interaction between light and nano- and micro-scale artificial structures fabricated by state-of-the-art microfabrication technologies, and applying them to optical control technologies. Laser processing technology itself is also an object of our research. We are exploring the science of laser processing and also developing new methods for fabricating micro three-dimensional structures using ultrashort laser pulses. For these purposes, we make full use of advanced spectroscopic techniques such as laser nonlinear spectroscopy and terahertz spectroscopy, as well as micro-nano processing and evaluation techniques.
A6 Ryusuke MATSUNAGA The Institute for Solid State Physics Light-matter interaction provides deep understandings of the fundamental properties of materials and how to control it artificially by light. Terahertz and mid-infrared light sources allows us to reveal elementary excitations in solids, cooperative phenomena in many-body systems, and functionality of novel materials. With developing state-of-the-art pulsed laser system, we explore THz-MIR extreme nonlinear optics and nonequilibrium dynamics in solids induced by intense light field.
