| Notes | LUO Wei, YUAN Sheng-Fu, ZOU Qian-Jin, LU Qi-Sheng （College of Opto-electronic Science and Engineering, National University of Defense Technology,Changsha 410073 ,China） Unusual spectral lines of the 4-3 vibration state transitions of DF molecules and the 3-2 vibration state transi- tions of HF molecules have been observed in the DF/HF lasers operated with cold pumping reaction. Several typical spectrums were given, and the gain coefficients of these fundamental spectral lines of the high vibration state were calcu- lated. Experimental results and theoretical calculations have shown that the kinetics process of these lines can not be explained by the cold pumping reaction only. The fluorine atom recombination and hot pumping reaction subsequently may be the main factors. The influences of hot pumping reaction and chain pumping reaction on the emission spectrum, gain and gain zone length of DF/HF lasers operated with the cold pumping reaction were discussed. 31-1577/TN chemical laser; spectral analysis; cold pumpi |
