Abstract: Based on the theory of electron impact excitation,the curves of electron impact-excitation cross sections q of S2(B-X) state can be calculated and the curves show that there are a threshold energy and a maximum value 10-16cm2 of electron impact excitation cross section q at the point of 1.8 time of threshold energy.According to the results,the laser threshold condition of discharge pumping S2 also is given out.The corrosion resisting and heat-resisting transverse pulse discharge apparatus of S2 is designed to provide the experimental system and the stable even glow discharge is obtained.The experimental research show that the small signal gain efficient at wavelength 419.4nm is 0.012cm-1.
