Abstract

The wavelength of CO₂ laser radiation is in the spectral range of 9-11μm. So the rapidly tuning TEA CO₂ laser is an ideal optical source and core parts of laser differential absorption lidar (LDIAL). To expand the spectrum of TEA CO₂ laser and the amount of the atmospheric gases controllable by the LDIAL, laser spectrum of carbon-13 oxygen-16 isotopic species of carbon dioxide is investigated. The spectroscopic constants and wavelength of the two laser band 00011-10001 and 00011-10002 are calculated. Using the spectrum analyzer the spectrum of the TEA CO₂ laser in which ¹³C¹⁶0₂ is used as working gas is obtained. The used laser is a rapidly tuning miniature TEA CO₂ laser. The cavity of the TEA CO₂ laser is 200 mm in diameter and 400 mm in length. The main electrodes are a pair of Chang's aluminum electrodes. Tuning mechanism consists of diffraction grating, trigger controller and high frequency stepping motor. The experimental wavelengths are in good agreement with the calculated data. Compared with common C0₂, the emission line range of ¹³C¹⁶0₂ is expanded toward the longer wavelength, the longest wavelength of the TEA ¹³C¹⁶0₂ laser is 11.347 μm.
