| Outline of Final Research Achievements |
Cavity-enhanced phase-matched coherent anti-Stokes Raman spectroscopy (CARS) for a novel tool to improve a molecular detection sensitivity of conventional intracavity Raman spectroscopy has been developed. We found an issue in the stability of a cavity resonant condition when both hydrogen and inert gas are filled in the cavity chamber. To stabilize the cavity resonant condition, a feedback control system for two beams having different wavelengths (fundamental: Ti:sapphire laser and Stokes: ECLD). This work will contribute to high-sensitive detection of radio-active hydrogen isotopes based on a phase-matched CARS technique.
