| Outline of Research at the Start |
本研究では、特異な電子状態を持つ固体結晶や構造制御したナノ物質・原子層物質を作製できる物質科学と最先端の高強度レーザー技術を融合し、強電場光科学の深化と応用展開を図ることを目指す。空間・エネルギー的に電子状態を制御したナノ物質とレーザーパルス電場により電子の運動や光学遷移を操作し、高次高調波発生などの強電場下で起こる新規な現象の探求と機構解明を行い、強電場光科学という新たな物質光科学分野の創成に挑戦する。

| Outline of Final Research Achievements |
By combining materials science - specifically the unique electronic states of solid-state crystals and nanomaterials - with cutting-edge laser technology, we have promoted research that deepens our understanding of high-field nonlinear photophysics and photonics. We have observed high-order harmonic generation from semiconductor nanocrystals, controlled electronic motion and optical transitions using laser-induced electric and magnetic fields, developed methods for observing electronic states in solids, and discovered quantum cooperative effects in electronically coupled nanocrystal thin films. We advanced fundamental optical science and technology for the next generation of photonics.
