摘　　要：本文研究了约束放电激励千瓦级基模ＣＯ＿２激光器。约束放电激励的思想核心是：利用正交或基本正交的电场或者电磁场在阴极位降区附近形成对带电粒子的捕集阱，由此产生对放电过程中从阴极发出的带电粒子的约束作用从而影响整个气体放电激励过程。A new gas laser──1kW TEM_(00) CO_2 laser── excited by the confined discharge has been studied in this paper. The confined discharge means that in the process of laser discharge,the or-thogonal electrical and electrical fields or orthogonal magnetic and electrical fields on the surface of cath-ode are used to confined electrons and ions in a trap or many traps of well designed shape. As an example of the applications of this excitation method,high efficient and high power CO_2 CW laser,in which the transverse magnetic field perpendicular to electrical field was used,has been studied in detail.
