| Outline of Final Research Achievements |
The mid-infrared light source and a remote sensing system was to promote the development in the project. The following points have been shown in the during the application period.
(1) We can detect the absorption-spectrum of the gas phase objects by the mid-infrared laser. (2) We improve the sensitivity by control of the noise, thermal noise and detection space, using the confocal optical system and cooling-spatial-filter. (3) By sweeping the incident position of the excitation light to PPMgSLT crystal that is fan-out structure, infrared laser has a wavelength sweeping ability of 3-4μm. (4) Portable laser radar can be detected scattering-light of laser from the mountain at the 1km. The state of the moutain-surface from the detected scattered signal is found in detail.
