【摘要】 <正>1965年第一台横向N₂激光器问世以来,出现了很多横向放电的激光器,其中大多数是Blumlein型或类似Blumlein型.现已实现纯N₂在大气压或更高气压情况下的工作,一般采用电极间隙窄到几个毫米或刀口电极,放电体积较小.为了得到大体积中的快速稳定的横向放电和提高转换效率,发展了各种预电离技术.最近几年国内曾陆续报导了电晕预电离在N₂激光器中的使用情况,我们的实验观察了紫外光预电离对N₂激光输出的影响.更多还原

【Abstract】 The technique and experiments of ultra-violet preionization in molecular N2 laser and He-N2 laser are described briefly. The experimental results showed a significant improvement in the homogeneity of laser discharge. With UV preionization, the output of atmospheric He-N2 laser has been increased by four times and an increase of 30 torrs of the optimum working pressure of molecular N2 laser is obtained.更多还原
