高速周波数掃引 (RAFS) レーザー分光法

抄録

The techniques of rapid frequency scanning of dye lasers, using electro-optic (EO), acousto-optic (AO) and mechanical scanners, are reviewed. Lasing characteristics in rapid scanning are experimetally and analyti-cally discussed. A novel technique of rapid-frequency-scan (RAFS) laser spectroscopy can determine line-profiles of atoms and molecules instantaneously within a single laser shot. Two types of scanners, an etalon driven by a PZT peizo-electrical element and an EO filter with a KDP crystal, are examined in this RAFS las-er system, Some examples of the RAFS laser spectroscopy to measure atomic line-profiles by a single lasershot are described.
