摘　　要：计算了Ｓ２（Ｂ－Ｘ）态电子碰撞激发截面，给出了放电泵浦阈值条件，设计研制了横向放电Ｓ２激光器及快脉冲放电电源。获得均匀的辉光放电，在中心波长４１９４ｎｍ处首次测到００１２ｃｍ－１的小信号增益系数。Based on the theory of electron impact excitation,the curves of electron impact excitation cross sections q of S 2( B-X ) state can be calculated and the curves show that there are a threshold energy and a maximum value 10 -16 cm 2 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 S 2 also is given out.The corrosion resisting and heat resisting transverse pulse discharge apparatus of S 2 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 .
