摘　　要：对管板式低气压放电结构、横流连续２ｋＷＣＯ２激光器以Ａｒ气取代部分Ｈｅ气进行了研究。Ｈｅ气的取代量（掺Ａｒ量）从２０％增加到６０％，工作气压在２．９３～４．２６ｋＰａ，放电电流在３～１１Ａ的范围，激光器放电稳定，运转正常，可获得良好的输出特性，如输出功率为１．７ｋＷ，电光转换效率为１６％。A JK 13 across flow CW 2 kW CO 2 laser of tube plan low gas pressure discharge structure, using argon helium mixing gas, was studied. The substituted amount of He gas (Ar doped amount) increased from 20% to 60%. When the working gas pressures were 2.93￣4.26 kPa and the discharge currents were 3￣11 A, the laser discharged steadly and operated normally. An output power of 1.7 kW and an effciency of electro optic conversion of 16 percent can be obtained.
