| Outline of Final Research Achievements |
The purpose of this study is to develop a mid-infrared laser spectrometer with “mid-infrared “optical fiber technology for detection of isotopologues. The laser oscillation and detection test with a mid-infrared quantum cascade laser, a mid-infrared fiber, a mid-infrared collimator, a small cell, and a mid-infrared detector showed that the laser oscillation-detection result through the mid-infrared fiber and collimators was good, however a fringe increase due to a small cell was found. As the results, the fiber-based laser spectroscopic system, without using the traditional optical lens system, could be possible even in the mid-infrared region.
