研究概要
光の振幅位相・偏光を自由に操作する技術を、物理・ 化学・生命科学から医療に至る幅広い分野に応用しています。主に以下の４つプロジェクトを推進しています。
① ベクトル電場波形整形パルスによる時間反転対称性の破れた量子系の生成と制御
ベクトル波形整形という三沢研独自の技術により、時間とともに偏光状態が任意に変化する光を生成する。それを用いて、生体分子における右手系と左手系物質の変換を目指す。
② 分子構造指標を用いた生体関連分子の細胞内動態観察装置の開発
位相制御コヒーレントラマン分光法という三沢研独自の技術により、顕微鏡下で生体関連分子の分布を画像化する装置を開発する。薬剤分子が生体 と相互作用する過程の解明を目指す。
③ 溶液化学のX線時間分解分光の開拓
X線自由電子レーザーSACLAを利用して、水溶液内での溶質分子が溶媒分子と相互作用する過程の解明を目指す。
④ 位相制御ファイバーレーザーを用いた実時間動的分子構造制御
イッテルビウムファイバーレーザーという次世代の光源を開発する。それを用いて、分子の化学反応で自由に反応生成物を作り分けることを目指す。

Summary
We apply the technology to manipulate arbitrarily the amplitude, phase and polarization of the light to a wide range of research fields such as physics, chemistry, life sciences and medical engineering.We are promoting mainly the following four research projects.
① Generation and control of quantum systems with time-reversal symmetry breaking by the vector electric field waveform shaped pulses
By use of our proprietary technology called vector waveform shaping, we generate the light whose polarization state is arbitrarily changing with time.We aim to realize conversion between right-handed and left-handed materials in biological molecules using this optical method.
② Development of observation apparatus for intracellular dynamics of physiologically active molecules using molecular vibrational spectra
By use of proprietary technology called phase controlled coherent Raman spectroscopy, we develop a laser-scanning microscope for imaging the distribution of biologically relevant molecule.We aim to elucidate the action mechanism of drug molecules interacting with biological systems.
③ Development of time-resolved X-ray spectroscopy for solution chemistry
By using the X-ray free-electron laser SACLA, we aim to elucidate the interaction process between solute molecules and the solvent molecules in aqueous solution.
④ Real-time dynamical molecular structure control using the phase-programmed fiber laser
We develop a cutting-edge ultrafast ytterbium fiber laser.We aim to produce selectively target species in chemical reaction of molecules.
