| Outline of Final Research Achievements |
An Er-doped fiber optical frequency comb was fabricated and its frequency was stabilized. The mode interval and offset frequency of the optical frequency comb were stabilized by using the reference signal from the cesium atomic clock mounted on the GPS satellite. By adjusting the control system, continuous operation was possible all day.
The frequency of the single mode Ti: Sapphire laser was precisely controlled based on this optical frequency comb. We have developed a high-resolution spectroscopy system using this light source system and a supersonic molecular beam spectrometer.
Using this laser beam, high-resolution spectroscopies of polycyclic aromatic hydrocarbons such as 1,2-benzanthracene and 9-methylanthracene using supersonic molecular beam were performed.
