Outline of Final Research Achievements

In this study, we have developed spectroscopy methods using optical vortex beam, which can detect the particle flow in the perpendicular direction of the beam. In optical vortex absorption spectroscopy and optical vortex saturation absorption spectroscopy, azimuthal Doppler shifts that are qualitatively consistent with the theory were observed. The amount of the azimuthal doppler shift was inversely proportional to the distance from the phase singularity. Meanwhile, the absolute value of the Azimuthal Doppler shift is several times larger than the theoretical expectation. Hence, it is necessary to continue improving the measurement system. Regarding the optical vortex LIF spectroscopy, it was confirmed that the effect of azimuth Doppler shift could not be observed with an optical vortex at topological charge 1. Therefore, we have developed a new higher-order optical vortex light source. We plan to proceed the measurements using the light source.

Academic Significance and Societal Importance of the Research Achievements

近年,様々な分野で高度に制御したレーザー光が利用されており,超高精度な周波数標準,超短パルスによる時間分解測定や超高エネルギー密度状態の実現等の極限的な研究開発が行われている.一方で,光の空間構造に関しては,あまり利用された例がなく,今後の光利用において発展の余地が大いに残されている.本研究課題は,プラズマの分光測定に光渦を用いることを提案しており,光の位相空間構造をプラズマの測定に積極的に利用する初めての試みである.光渦吸収分光および光渦飽和吸収分光では,平面波を用いて観測される通常の分光スペクトルとは大きく異なる結果を得ており,光の位相空間構造制御による新しい分光技術の可能性が示された.
