Outline of Final Research Achievements

We showed a conceptually novel idea that nonlinear optical process could be manipulated in a variety of ways by controlling the relative phases among the electromagnetic fields relevant to its nonlinear optical process. We established such basis theoretically and experimentally. We also opened a way to build a new laser technology, that is, single-frequency widely tunable laser in the vacuum ultraviolet region.

Academic Significance and Societal Importance of the Research Achievements

60年の歴史を持つ非線形光学の体系に、非線形光学過程を様々な形態に人為的に操作するという質的に新しい可能性を付与することができた。また、真空紫外域に実用レベルで利用可能な単一周波数波長可変レーザー技術を構築するための土台をつくることができた。真空紫外域は光と物質の相互作用が極めて強い波長域である。この研究で築かれた成果を土台として、原子核遷移を用いた次々世代の光周波数標準や反水素のレーザー冷却など魅力的な学術的展開が展望される。
