Outline of Final Research Achievements

A nonlinear detector yields the interference fringes of the fundamental and high-harmonic waves in different frequency regions. We analyze the formation of nonlinearly detected interference fringes. We demonstrate, for the first time, that the interference fringes of high-harmonic waves can also be used to determine the position of zero optical path length difference between reference and object mirrors.
High-accuracy measurement using phase information of fringe patterns, that is not much affected by amplitude noises than amplitude information, in a pulse-train interferometer is demonstrated in this study. However, the selection criteria for spectral components of the measured interferogram for regeneration of phase information are not obvious. In this work, a frequency pair model is proposed.

Academic Significance and Societal Importance of the Research Achievements

2009年、フェムト秒レーザーによるフェムト秒光周波数コム(以下では光コム)が計量法の特定標準器(長さ)として採用された。光コムの中心波長は通信用の光ファイバーの波長帯Cバンドと一致する。そのため、光コムが光ファイバー中を伝搬した時、光の損失が少ない。レーザー光がより長距離に伝搬できる。本研究はこのようなシステムができた時、送られた光信号から、どのように長さ計測を実現するのかを研究している。すべての長さ計測とそのトレサビリティは光ファイバーを介して、光コムによりリアルタイムで統一されることにつながる。
