Paper 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.
