摘要：

This paper describes a CW sub-millimeter waveguide discharge-pumped DCN laser operating on 190 and 195 mum lines. The laser discharge length is 3 m, and the resonator length is 3.4 m. The resonator cavity consists of a pyrex tube of 54 mm diameter and two plane reflectors against its ends, one is a plane mirror, the other is a metal mesh. After optimization of various parameters, such as the N-2:CD4:He gas mixture, the pressure and the discharge current, the wall temperature and the output couple, this laser delivers 200 and 220 mW on the 190 and 195 mum lines, respectively, for EH11 mode.
