Influence of additional gas on TE N2 laser output

This paper emphasizes the influence of additional SF6 and He on TE N2 laser output at 3371Å. The experimental results show that the laser output power can be increased about 2 times, by adding SF6 in pure N2, and when the ratio of N2:He is 1:2～1:3, the laser output will be increased by 30%～70%. The influences of the additional He on the electron temperature, electron density and electron energy distribution are also studied. Therefore, the fact that the additional gas can improve the laser output is reasonably explained.
